Fwd: [Serusers] Multiple potential memory leaks in ser

by Jiri Kuthan

Maxim, Thank you very much for your report. I'm not the code owner who has the last word, but I agree there is a memory leak. It seems to me that insert_new_lump family is ok as long as the calling functions care to free their lump buffers on failure -- that's where the leak lives. Which imho happens at few places on CVS: +insert_new_lump_before - save_ruri in rr/loose.c - textops/append_hf_helper.c - (on contrary, it is ok in maxfwd/add_maxfwd_header, rr functions calling insert_RR, and msg_translator.c) +insert_new_lump_after - search_append_f in textops.c - replace_f in textops.c - (ok in build_req_buf...) The memory leak is unlikely to occur, as it is triggered by lack of private memory which (unlike shmem) hardly gets exhausted -- so operation is fortunately not affected. It will be fixed in the next release. -Jiri ps -- I swear on cscope :) >Folks, > >I've noticed that there are multiple potential memory leaks in SER. >The problem is that if a insert_new_lump*() function returns a NULL >for some reason (currently the only condition is memory allocation >error), it doesn't free the memory buffer passed to it and most of >the code doesn't care to deallocate that buffer after NULL is returned. >It could be easily fixed and probably needs to before the next version >is released. > >Thanks! > >-Maxim >_______________________________________________ >Serusers mailing list >serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Question on gateway routing through UA proxy

by John Todd

Goal: To learn about ser in a "non-critical" and very small PBX-like environment so as to be able to understand nuances of the system in a production environment at a later date at various firms whose owners who have expressed to me a high degree of interest in SIP call routing for larger enterprise and CLEC implementations. Sub-Goal: to make all calls into and out of my house routed via IP to alternate destinations based on ser routing configuration. I have subscribed to a long-distance plan via "iconnecthere.com", I have a PRI gateway configured at a remote location (for calls into two area codes only) and my plan is to have a Cisco 2610 with FXO card for terminating my "local" phone line. My house phones are all Cisco ATA-186 devices. Based on called number, my calls will be sent to the iconnecthere.com SIP service, the Cisco PRI gateway, or the Cisco 2610 single-line gateway. Calls will also be routed appropriately based on number called on an inbound basis from any of those three gateway systems (PRI, 2610, or iconnecthere.com) Progress: I have phone-to-phone calling working well, and I have phone-to-PRI gateway calling working well in both directions. I have not yet received the 2610, so I do not have the single-line analog gateway running, but I don't expect any issues with that system, as I understand the Cisco implementation of inbound/outbound VOIP sessions. Problem: My "iconnecthere.com" account is a username/password protected account which (of course) requires a UA at my side of the connection. To forward calls from the various phones in the house, I would need to have something re-write my username/password requests on the fly when they are sent out to the iconnecthere.com SIP proxies/gateways. My first assumption is that I'll need a (sigh) B2BUA to act as a gateway, running (for convenience) on the same UNIX platform as ser. After thinking about it for a while, I am uncertain if that is required, but at this point I can't determine what I need to do. I would appreciate hints on: a) Wether I need a B2BUA at all, and if not, what config options should I be looking at in ser? b) If I do need a B2BUA, what would you recommend? I'm using OpenBSD as my platform, and (personally) I'd like to stay away from Java for the moment. Continuing discussion: I could see this as a fairly useful toolkit trick for a small business who wants to replace their phone switch with SER or ser-like systems. If you've got an office with 10 people, it may make economic sense to simply get "generic" accounts with a SIP long distance gateway provider like iconnecthere.com (there are others) and allocate each of those accounts to individuals in the organization. This is not a solution for a large-scale operation for the various reasons outlined in the http://www.iptel.org/info/trends/#b2bua texts, but the number of small-scale shops out there is very large and a simply understood package (and simply billed) is what would be desired for many places who still use under ~10 analog lines for outbound dialing from their PBX. Any outbound calls to certain prefixes would always be pushed through a specific account for LD calling. Additionally, inbound calling through a similar service would have to also come in via the same mechanism, with a REGISTER request being sent by the B2BUA and all subsequent calls being routed through the SER proxy. PS: I'd appreciate any open-source hints on how to get an ATA-186 (v2.15) running behind NAT with ser on the "outside" of the NAT, without statically configuring the "NAT" address on the ATA-186 every time the outside address changes. Lots of keyword matches found on Google, but very few clues to be scraped from the resulting documents as to "how" do it from the server side. JT

[Serusers] Too much shared memory demanded: 33554432

[Serusers] Troubles using b2bua as a accounting and call duration limiting module for SER router

by Maxim Sobolev

Dear Sirs, I am having some strange problems when trying to use b2bua for accounting and call duration limiting with SER proxy server. The idea is simple: since the SER can route SIP messages depending on their source address, we can force incoming SIP messages to be passed to B2BUA for accounting purposes first, and after the same request re-enters the proxy from B2BUA pass it to the final destination. Call flow looks like the following: ----- |UA2| ----- ^ | |4 | ----- 3 ------- ----- 1 | |<-----------| | |UA1|---->|SER| 2 |B2BUA| ----- | |----------->| | ----- ------- For some reason, it doesn't work in such configuration. The problem is that B2BUA's UAC keeps resending `200 OK' replies ingnoring ACKs it receives from UA2 until timeout hits, after which it considers the call dead, despite the fact that both UA1 and UA2 think that the call is established. Maybe it has something to do with the fact that it sends to and receives messages from the same host (SER), but I don't think that this should be a problem, since those two call legs have different call id's, so that b2bua should be able to distinguish between them easily. Attached please find tcpdump logs of one such session, here 192.168.1.1 is UA1 (originating), 192.168.0.9 is UA2, 192.168.1.100 is the host running both SER and B2BUA (the former uses port 5060, while the latter - 5065). There are two files: ser-b2bua.log is the log of udp exchange between SER and B2BUA and ser-ua1ua2.log - log of exchange between SER and UA1/UA2. Any ideas are appreciated. Thanks! -Maxim

Does your nathelper module work now? Attached please find more fresh patch with several bugs smashed. It is probably the last one on this topic, because it works reasonably well and we now have moved to adjusting b2bua for our needs (mostly radius auth/acc).

[Serusers] Multiple potential memory leaks in ser

by Maxim Sobolev

Folks, I've noticed that there are multiple potential memory leaks in SER. The problem is that if a insert_new_lump*() function returns a NULL for some reason (currently the only condition is memory allocation error), it doesn't free the memory buffer passed to it and most of the code doesn't care to deallocate that buffer after NULL is returned. It could be easily fixed and probably needs to before the next version is released. Thanks! -Maxim

[Serusers] [RFC] ideas about new dialog module

by Maxim Sobolev

Hi, I am thinking about writing a new module for SER, which will track SIP dialogs and will serve as an abstraction layer for other modules, much like the tm module now. We need such module for 2 reasons: 1. Call accounting. Our billing engine is based on the assumption that a node provides accounting information for completed calls, not for individual transactions. It is easier for us to extend proxy with similar features than to modify billing engine to do transaction matching. 2. Debit card application. Currently, there is no way to use SER for debit card applications, where it is necessary to set the maximum duration of the call and terminate it forcefully if that duration is exceeded. The raw idea is as follows: - the module will register callbacks with tm.register_tmcb(), probably TMCB_REQUEST_IN and TMCB_REPLY_IN ones and will match INVITEs to BYEs keeping information about the state of ongoing sessions in the shared memory. - the module will provide interested modules with ability to register several callbacks, i.e. on dialog creation/teardown and yet another callback on dialog timeouts (more about that below). - the module will provide utility functions for forceful termination of any ongoing dialog. - when invoking dialog creation callback function, the module will give the function opportunity to install a timer on that dialog, so that if the dialog is still active after timer expires, then some action is performed. For example, in the debit card applications, in such case the accounting module can decide to forcefully terminate a dialog. What do you think? -Maxim

[Serusers] radius_auth problem

by Joe_chen

hi, I have a problem with radius_auth, i use raidus_auth module as www-authentication ,but something is wrong, the free-radius server need the PW_PASSWORD attribute for authentication, while the ser's radius_auth module doesn't send the PW_PASSWORD attribute, i can't find the password from the REGISTER message, there is a NONCE like nonce="3e1947180000000040c0e6240c7f8145a64eb654ce9a14e0" and encrypted with MD5. Do i need get the user's password and how to get user's the password? please help. thanks.

[Serusers] problem with phone authentication

by lgfausak＠august.net

This works with my eStara soft phone client: --------------cut # route[1], REGISTER block # REGISTER messages destined for our realm are forwarded here. # after a successful registration a customer can receive calls. # route[1] { if(!www_authorize("augustvoice.net", "subscriber")) { www_challenge("augustvoice.net", "0"); break; }; log("here is a register"); if(!save("location")) { sl_reply_error(); }; break; } ---------------uncut However, when I try to get my Cisco 7960 to authorize it fails.

[Serusers] ata

by Jan Janak

Hello, your messages about CISCO ATA reminds me that I have also one (a preproduction unit originally made by Komodo), so I upgraded firmware to 2.15 and tried it behind a symmetric NAT. It works, I had to enable portforwarding for signalling and media and setup properly outer address of the NAT box in the phone. Once you finish your NAThelper module, I would like to give it a try and see if it works without modifications of the NAT box. So I can help you to test the code if you want. regards, Jan.

[Serusers] [HEADS UP] security vulnerability in ser 0.8.10

by Maxim Sobolev

Folks, While playing with SER I found that I can trigger repeatable crash when doing REGISTER multiple times. Quick glance at the code in question revealed that indeed, when constructing reply to REGISTER message, SER uses fixed-lengh buffer to put all non-expired contacts for that user and doesn't bother to check for overflow. The bug could be easily exploited by a complete stranger on servers that don't perform authentification of REGISTER requests, and by an user with a valid credintals on server that do authentification. Mounting attack leads to denial of service. Attached please find fake REGISTER message, which if sent to open server kills it (nc -u my.sip.server 5060 < register.killser), and patch to fix the problem. -Maxim

[Serusers] Password problem with ser and mysql

by Klaus Darilion

Hello! I have sucessfully installed the ser server (0.8.10 from rpms) with an mysql database. When I use the standard password for the user "ser" everything works fine. But if I change the password from "heslo" to a new one, for example "klaus" instead of "heslo" (of course in the mysql-database und in the config file) the ser server can not start up. Following are some different configurations and my suggestions what could be the problem. ser.cfg: modparam("auth", "db_url", "sql://ser:heslo@localhost/ser") mySQL-root-password: XXXXX mySQL-ser-password: heslo ---> works fine ser.cfg: modparam("auth", "db_url", "sql://ser:klaus@localhost/ser") mySQL-root-password: XXXXX mySQL-ser-password: klaus ---> doesn't work: connect_db(): Access denied for user: 'ser@localhost' (Using password: YES) should work, so I tried another user ser.cfg: modparam("auth", "db_url", "sql://root:XXXXX@localhost/ser") mySQL-root-password: XXXXX mySQL-ser-password: heslo ---> works fine ser.cfg: modparam("auth", "db_url", "sql://root:XXXXX@localhost/ser") mySQL-root-password: XXXXX mySQL-ser-password: klaus ---> doesn't work: connect_db(): Access denied for user: 'ser@localhost' (Using password: YES) very strange, because I told ser to connect as root. Is ser using the default user/password instead of the configured one? ser.cfg: modparam("auth", "db_url", "sql://root:YYYYY@localhost/ser") mySQL-root-password: XXXXX mySQL-ser-password: heslo ---> doesn't work: connect_db(): Access denied for user: 'root@localhost' (Using password: YES) of course it doesn't work, wrong password. So ser cares about the settings in ser.cfg So my suggestion is that ser connects several times to the database whereas one time it uses the configured user/password and another time it uses the default user/password - maybe a bug in the auth module? Or does somebody of you changed the password successfuly? It would be nice if you can help me. Thanks, Klaus My system is: Linux version 2.4.18-14 (bhcompile(a)astest.test.redhat.com) (gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)) #1 Wed Sep 4 12:13:11 EDT 2002 MySQL 3.23.52 ser-0.8.10-2.i386.rpm ser-mysql-0.8.10-2.i386.rpm

[Serusers] problems getting started with ser/serweb

by Stephan Reiff-Marganiec

Hi, I have installed ser and was amazed how easy it was to install (we have previously experimented with sipd, which finally runs ...). I have run through the archives and also looked at all the documentation, but some things still don't work. I use kphone 2.11 as client, but have tried sipc on a solaris box to the same extend. I am running kphone and ser 0.8.10 on redhat 8. MySQL is 3.23.52. I have set the domain/realm things to cs.stir.ac.uk and restarted ser. I have then set up a user using "serctl add srm test srm(a)cs.stir.ac.uk". Now, on serweb in user_interface/index I cannot login with this user.

[Serusers] SER on masqueraded/NAT connection

by Craig Graham

I have a Linux box at home acting as a masquerading/NAT gateway for a few Windows PCs, and have installed SER on there in order to use MS Messenger to talk to people outside. SER appears to be working in that I can get Messenger up on two PCs, connect to SER and set up a voice connection between the two PCs. However, I cannot connect to people offsite. Relevant IPChains entries are target prot opt source destination ports ACCEPT udp ----l- anywhere anywhere any -> 5060 ACCEPT udp ------ anywhere anywhere any -> 7070:7080 I have made no changes to the default SIP configuration; it is working as installed by the rpm package ser-0.8.10-1.i386.rpm. A browse through the mailing list archive and through the admin guide doesn't show anything obvious. No errors are reported to /etc/messages or /etc/syslog and serctl moni does not show anything that looks relevant. Does anyone have any suggestions? -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/

[Serusers] Moving SDP-related functions into core parser

by Maxim Sobolev

Folks, My nathelper module will need to tweak body of the messages, therefore it will be third module after im and sms that needs body-related functions. IMO it would probably make a lot of sense to move those functions into core parser, so that modules will not have to import im module just to use one or two utility functions. Please let me know what do you think. Thanks! -Maxim

[Serusers] Access control on PSTN gateways

by Michael Graff

We have a group of people who run their own SIP servers (some are SER, some are not) and we are going to be sharing a PSTN gateway (Cisco box). I need to rewrite the identities for the users of our gateway into something that can be presented to the PSTN gateway for billing purposes. We don't want to do that mapping on the gateway itself, for various reasons. How do people handle this situation? Is it wise to put all functionality for user handling and incoming call handling and forwarding to another place in the same SER server? --Michael

[Serusers] encryption on authorization

by Karsten Knüttel

Hi there, In a REGISTER case there is a HeaderField AUTHORIZATION. The usual encryption algorithm is "MD5". Is it possible to REGISTER without any encryption? Please give a statement if I understood everything right or correct me: Digest Username => not encrypted; realm =>not encrypted; URI =>not encrypted; Nonce => encrypted => is Password? Response => encrypted => what´s that? Thanks! P.S.: I sniffered the network traffic when I registerd,established a VoIP-Connection and ended my call. Etherreal, the snifferprogramm, does understand SIP and SDP so I could easy protocol and understand what was going on.

[Serusers] How to add fields in INVITE SDP ?

by David.Rio＠alcatel.fr

Hello I am using SER in a test environment as a proxy server. I would like it to add additional fields in the SDP of an INVITE message for some test needs. (e.g. add 'a=sendonly'). Is it possible ? If not possible, do you think it would be difficult to add a function addSdp(<string>) that would append a given string to the SDP of the current message and alter the 'content_length' header field ? I do not see in the 'sip_msg' structure any pointer to the body part of the message ; only pointers to header fields.

[Serusers] multiple domain madness

by Michael Graff

Using multiple domains in one server is pretty hard. The schema even fights with me. I can't have both "graff" in the "isc.org" domain and "graff" in the "flame.org" domain, for instance, at least with the same user name. I think the unique field there should be a <user, domain> tuple. Additionally, all tables should probably grow a domain column, and lookup() would take that as an argument (defaulting to the host-portion of the URI, probably) That also makes things easier on routing rules, and on aliasing, and on user interfaces, at least IMHO. Are there any plans to make this sort of thing much easier? If not, I may decide to hack on it a bit and see what I come up with. Of course, I'd also like to replace the scripting language with embedded Perl, but... :) --Michael

[Serusers] SER as UAS

by Viji Krishnan

Hi, I downloaded SER yesterday and I am trying to run it as a UAS. I am using the sample configuration uas.cfg. I modified it so that on receiving an INVITE I send a 200 OK. Now the problem is when I use the t_reply command to send the 200 OK, it doesn't add any SDP part to it. Is there anyway an SDP can be added to the 200 OK response to the INVITE.

Re: [Serusers] FCP support in SER

by jaime.gill＠orange.co.uk

Is anybody aware of any SIP ALG developed or being developed for linux/freebsd? Jaime PS: If nobody is looking at the FCP client side for SER, I would like to contribute in my spare time. Please let me know where should I start and may be I could give it a try. Jiri Kuthan <jiri(a)iptel.org> on 08/01/2003 21:39:20 To: Jaime GILL/EN/HTLUK@HTLUK serusers(a)lists.iptel.org cc: Subject: Re: [Serusers] FCP support in SER This piece of work is stalling for some reasons. First, the gentlemen who was supposed to integrate an FCP client silently stepped away from this assignment. FCP server on linux is working. The other problem with FCP is there are no real standards. I was expecting the Midcom WG in the IETF to come up with one. Instead, it spent two years with doing things whose use I very strongly doubt. If there is any volunteer on this mailing list who would wish to complete or create the FCP client module, we will be glad to provide guidance. Users willing to traverse NATs may consider STUN/UPnP or ALGs as an alternative solution. Users willing to traverse firewalls may need to use an ALG or VPN technology. Unfortunately, NAT/FWs break too many things and there is no one-size-fits-it-all solution addressing all scenarios. -Jiri At 06:14 PM 1/8/2003, jaime.gill(a)orange.co.uk wrote: >Hi, > >I am wondering if this is the right place to ask, but here it goes. > >Is the SER software going to incorporate the client side of FCP (Firewall >Control Protcol) as a module at some point? > >Regards, > >Jaime > > > >******************************************************************************* >Important. >Confidentiality: This communication is intended for the above-named person and >may be confidential and/or legally privileged.

[Serusers] ser up and running, now on to voice mail / conferencing

by Michael Graff

I got SER up and running with a whopping total of three "domains" being served on the same server. It was mostly painless, if missing some features I'd like to have seen (more on that in later messages.) What open source products are people using for voice mail, voice menu prompts (press 1 for sales, press 2 for the executative restroom) and for conference calls (which include PSTN calls as well as IP phones)? --Michael

[Serusers] SIP Symmetric Response support in SER

by Maxim Sobolev

Hi, Are there any plans to add SIP Symmetric Response support (http://www.iptel.org/info/players/ietf/firewall/nat/draft-ietf-sip-symmetri…) into SER, so that it would be possible to use compliant UAs behind NATs with SER being on a public IP? The idea is simple: when the SIP packet is received from UA, the server checks if an empty `rport' parameter is present in the first Via field, and if yes then compares IP:PORT in the first Via header with the actual IP:PORT this request came from, and adds `received' and `rport' parameters into the header if either doesn't match before forwarding request further. Then, when replying or forwarding the request, the server checks if any of received or rport is present and uses it instead of the UA-provided values in corresponding Via header. Please let me know if there are work in progress on this, so that I will not have to reinvent the wheel. Thanks! -Maxim

[Serusers] acc problem

by Joe_chen

hi, i have met the same problem with acc. i can get the invite message for accounting,but i can't get the bye message, i also capture the udp packages on ser server, i use MSN for UA, i find the sip messeges like: invite,100 trying,180 ringing ,200 ok(for invite),but when i hangup, there are not bye message, it's like sending bye message from UA to UA directly,while not going throug ser server,so there is not BYE message for accounting, is it true? how to get the bye message for accounting? please help. my ser.cfg is like: .. loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/acc.so" #loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/print.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" .. modparam("acc", "db_url","sql://ser:heslo@localhost/ser") modparam("acc","report_ack",1) modparam("acc","log_level",1) modparam("acc", "acc_flag", 1 ) modparam("acc", "missed_flag", 3 ) # -- tm params -- modparam("tm", "fr_timer", 10 ) modparam("tm", "fr_inv_timer", 20 ) modparam("tm", "wt_timer", 10 ) .. route{ # initial sanity checks -- messages with # max_forwars==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (len_gt( max_len )) { sl_send_reply("513", "Message too big"); break; }; # Do strict routing if pre-loaded route headers present rewriteFromRoute(); # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("192.168.139.125", "subscriber")) { # www_challenge("192.168.139.125", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; # set for accounting (the same value as in acc_flag!) if (method=="INVITE" || method=="BYE"){ setflag(1); # ... and also report on missed calls ... note that reporting # on missed calls is mutually exclusive with silent C timer # setflag(3); }; # forward to current uri now if (!t_relay()) { sl_reply_error(); }; } thanks!

[Serusers] Problems compiling SER with radius support

by Maxim Sobolev

Dear Sirs, Our company is currently evaluating several freely available SIP proxy/registrars to extend our VoIP billing engine, which currently only supports H323, to support SIP as well. We found SER to be one of the best for our needs: speed, documentation, flexibility - everything is great. Hovewer, since our billing engine uses Radius for AAA, we need to get Radius modules working. Unfortunately, we can't compile radius modules with virgin radiusclient 0.3.2 as suggested in documentation - it seems that some SIP-specific changes need to be applied to radiusclient headers, see the following log: gcc -fPIC -DPIC -pipe -O -mpreferred-stack-boundary=2 -march=pentium2 -funroll-loops -Wcast-align -Wall -minline-all-stringops -malign-double -falign-loops -DNAME='"ser"' -DVERSION='"0.8.10"' -DARCH='"i386"' -DOS='"freebsd"' -DCOMPILER='"gcc 3.2"' -D__CPU_i386 -DCFG_DIR='"/usr/local/etc/ser/"' -DPKG_MALLOC -DSHM_MEM -DSHM_MMAP -DADAPTIVE_WAIT -DADAPTIVE_WAIT_LOOPS=1024 -DDNS_IP_HACK -DUSE_IPV6 -DDBG_QM_MALLOC -DFAST_LOCK -DHAVE_GETHOSTBYNAME2 -DHAVE_UNION_SEMUN -DHAVE_SCHED_YIELD -DHAVE_SOCKADDR_SA_LEN -I/usr/local/include -c acc.c -o acc.o acc.c: In function `radius_log_reply': acc.c:125: `PW_SIP_METHOD' undeclared (first use in this function) acc.c:125: (Each undeclared identifier is reported only once acc.c:125: for each function it appears in.) acc.c:136: `PW_SIP_RESPONSE_CODE' undeclared (first use in this function) acc.c:156: `PW_SIP_FROM_TAG' undeclared (first use in this function) acc.c:189: `PW_SIP_TO_TAG' undeclared (first use in this function) acc.c:213: `PW_SIP_CSEQ' undeclared (first use in this function) acc.c:288: `PW_SIP_TRANSLATED_REQ_URI' undeclared (first use in this function) acc.c: In function `radius_log_ack': acc.c:434: `PW_SIP_METHOD' undeclared (first use in this function) acc.c:442: `PW_SIP_RESPONSE_CODE' undeclared (first use in this function) acc.c:461: `PW_SIP_FROM_TAG' undeclared (first use in this function) acc.c:491: `PW_SIP_TO_TAG' undeclared (first use in this function) acc.c:514: `PW_SIP_CSEQ' undeclared (first use in this function) acc.c:588: `PW_SIP_TRANSLATED_REQ_URI' undeclared (first use in this function) acc.c: In function `rad_acc_request': acc.c:733: `PW_SIP_METHOD' undeclared (first use in this function) acc.c:744: `PW_SIP_RESPONSE_CODE' undeclared (first use in this function) acc.c:764: `PW_SIP_FROM_TAG' undeclared (first use in this function) acc.c:797: `PW_SIP_TO_TAG' undeclared (first use in this function) acc.c:821: `PW_SIP_CSEQ' undeclared (first use in this function) acc.c:904: `PW_SIP_TRANSLATED_REQ_URI' undeclared (first use in this function) Would you be so kind to provide us with your changes for radiusclient or point out where that modified version can be downloaded? Thank you in advance! On a separate note I would like to ask you to let me know if there is any progress on pre-paid module discussed on this list recently. Since we will also need this functionality, perhaps we can team-up to implement it. Sincerely, Maxim Sobolev PortaOne Ltd

Re: [Serusers] acc question.

by lgfausak＠august.net

I really hate answering my own question :-) > } else if(method=="BYE") { > setflag(1); > forward(uri:host, uri:port); I changed this to t_relay() and then I get the BYE ACC output in the syslog file. This explains something else (I think). Sometimes the BYE would work, sometimes it would not make it all the way to the other device (either the PSTN gateway or the UA). That is probably because forward() simply bounces the packet via UDP and the UDP can fail ??? t_relay() retries??

[Serusers] acc question.

by lgfausak＠august.net

Hi, I am trying to create a basic script for routing calls to and from the PSTN. I have experimented with many scripts over the last month, this included script is an example. I can use a UA on my laptop called 'estara' and REGISTER with my ser sip server. I can make a phone call (INVITE) to the PSTN. I can hang up the call from either end (BYE) and everything seems to work well. I am trying to get accounting working. I see the call acceptance record in my syslog file: Jan 7 00:21:09 build ser[3507]: ACC: transaction answered: method=INVITE, i-uri=sip:92143357976@build.august.net, o-uri=sip:2143357976@64.90.42.16:5060, call_id= 847b3d22-131d-46b0-abcb-dc8e6a9f32b5(a)192.168.100.100, from= greg <sip:1107@build.august.net>;tag=3a7b9c52, code=200 However, I can't get the 'BYE' event to record the transaction to the syslog file.

Hi All, I am newbie of this field, thanks everyone help me. I am interesting in B2BUA, however, except some brief defination in 3261, I could not find any further defination or how to implement about B2BUA, I noticed that SER could be implemented as a B2BUA, where can I find some implementation? or where can I get any description?

[Serusers] Connecting to ser with MS Messenger

by Joseph McDonald

Hi, I've got ser installed and running (0.8.10 on Linux 2.4.18-18.8.0) I attempt to connect to it with MS "Windows Messenger" version 4.7.0104 on WindowsXP, but it never connected and I don't see anything in the logfile showing even an attempt to connect. Just to make sure that I didn't have any firewall rules blocking access, I wrote a little script to connect to port 5060 on the sip server and send it "Asdf\n", that appeared to work fine, as this appeared in my log: Jan 6 10:57:39 dell1 /usr/local/sbin/ser[14077]: ERROR: parse_first_line: message too short: 5 Jan 6 10:57:39 dell1 /usr/local/sbin/ser[14077]: ERROR:parse_first_line: bad message Jan 6 10:57:39 dell1 /usr/local/sbin/ser[14077]: ERROR: parse_msg: message=<Asdf > Jan 6 10:57:39 dell1 /usr/local/sbin/ser[14077]: ERROR: receive_msg: parse_msg failed So it appears that packets can get to the sip server fine from the machine that runs the Messenger client. I also ran serctl moni and didn't see any different output when I tried to connect with Messenger, i.e. there is no indication that a connection attempt is even made. Is there another IM client I can try connecting with? Any other tricks to know about Messenger other than what I found at: http://www.iptel.org/ietf55/use_msn.html BTW, this is using the mysql module and I created a user with serctl Jan 6 10:53:50 dell1 ser: ser startup succeeded Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14068]: mod_init(): Database connection opened successfuly Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14068]: INFO: udp_init: SO_RCVBUF is initially 65535 Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14068]: INFO: udp_init: SO_RCVBUF is finally 131070 Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14068]: INFO: udp_init: SO_RCVBUF is initially 65535 Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14068]: INFO: udp_init: SO_RCVBUF is finally 131070 Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14080]: INFO: fifo process starting: 14080 Jan 6 10:53:50 dell1 /usr/local/sbin/ser[14080]: SER: open_uac_fifo: fifo server up at /tmp/ser_fifo... thanks, -joe

[Serusers] error: max nr of branches

by Daryl Jones

I'm seeing the following errors in syslog when I place a call to one particular URI in my system. There are 5 devices registered to receive calls for this URI. Is this a problem? Is there a limit to how many telephone sets can have the same number appearance? Jan 3 12:15:44 sip /usr/sbin/ser[9845]: lookup(): Error while appending a branch Jan 3 12:15:44 sip /usr/sbin/ser[9845]: USRLOC DB lookup not found... Jan 3 12:15:52 sip /usr/sbin/ser[9846]: ERROR: append_branch: max nr of branches exceeded
