[OpenSER-Users] Parallel forking to loopback problem - for ringing multiple numbers at same time, simulring

by Dave Singer

by the way, I'm trying this using openser 1.3.0-pre1-notls from latest svn of trunk as of 12-4-07 I'm trying to do findme logic.. Call comes in, lookup settings for where it is supposed to go. >From the settings I find that the user wants it to ring a friends home phone, a cell phone, and the home ata associated with account. To keep voicemail handled by the home account and not by one of the places that they are forwarding to they want voicemail to be triggered after 15 seconds. The friends home phone is actually one of our accounts and has two ata's associated with it that register as the same sip user and they have it also ring a cell phone and the account sends the call to voicemail after 18 seconds. Psudo Call flow/Logic of what I have so far. Call comes in to openser for 555/123-4567 pull from usr_preferences settings for the call destination number. so I get a stack of avps $avp(s:brahch_uri) from usr_preferences like this: sip:5551239876@127.0.0.1 sip:localuser3@127.0.0.1 sip:5553216548@127.0.0.1 I do diversion header then branch for them with: avp_pushto("$br", "$avp(s:branch_uri)" I drop the local branch. The branched calls come in as expected and verify that it is a valid intentional loopback by testing: if ( ruri =~ "127.0.0.1" && dst_ip == 127.0.0.1 ) { < mark as valid loopback > } Like the beginning of the original call I lookup where they should go and if the user in the diversion header is allowed to send them there (PSTN) In this case one call would be sent out through the PSTN gateways with full failover logic, another would call the device associated with the account by doing a lookup("location") and the third, (the one to the friend that our customer) would add another diversion header and start another parallel fork with loopback for the cell phone and two ata's When I test with a simple forward to a single PSTN number, in the loopbacked session, I rewrite the ruri accordingly with real dest user and real ip address. the ruri shows what I want in the logs just before t_relay and exit and in branch_route[1] after last log entry from branch_route, I have in the log: ERROR:core:udp_send: sendto(sock,0xb619d954,1376,0,0xb619ba6c,16): Invalid argument(22) CRITICAL:core:udp_send: invalid sendtoparameters one possible reason is the server is bound to localhost and attempts to send to the net ERROR:tm:msg_send: udp_send failed ERROR:tm:t_forward_nonack: sending request failed Then I have log entrys from onreply_route[1]: Reply - S=100 M=INVITE RURI=<null> src_ip = 127.0.0.1 Reply - S=477 M=INVITE RURI=<null> src_ip = 127.0.0.1 not the real world IP address of the other server I set in the ruri and there is nothing in the logs on the intended server or the local server indicating routing logic for an invite failed I'm woundering if the TM module, while processing the invite in the loopback, is matching up the transaction with the session that originated the loopback and using the settings and status from it. Any Ideas, Thoughts, HELP!!? Or is OpenSER just not ready for this yet? Thanks Dave

[OpenSER-Users] uac_restore_from problem

by Zoltán Kovács

Dear Colleagues, first of all, thank you for the great software which is a very nice and convenient way to build up a stable VoIP telephone system! We already have a working system based on OpenSER and Asterisk. After many experiments I finally raise this question to you because I cannot figure out the solution. The problem described on http://www.openser.org/pipermail/users/2006-January/002747.html seems to be very similar to mine. I am using openser-1.1.0-9etch1. I tried to replace the FROM variable as follows: loadmodule "uac.so" modparam("uac","from_restore_mode","auto") ... route { ... avp_write("$fU", "$avp(s:display)"); avp_write("$fU", "$avp(s:dispuri)"); avp_subst("$avp(s:display)", "/^36(.*)/06\1/"); avp_subst("$avp(s:dispuri)", "/^36(.*)/sip:06\1@datanet.hu/"); uac_replace_from("$avp(s:display)", "$avp(s:dispuri)"); ... } Unfortunately nothing seems to happen: no change is made on several VoIP telephones, including X-Lite as well. loose_route() and record_route() were also used in my configuration. Could you please help me what I am missing here? If needed, I can also send a full config file. Thank you in advance, Zoltan Kovacs sysadmin

[OpenSER-Users] Problem with setting the Acct-Authentic Radius Attribute

by Dan-Cristian Bogos

Folks, I am trying to make use of Acct-Authentic to identify authenticated sessions inside accounting packets. All ok, no problem with dictionaries, but when it comes to receiving the value in freeradius server, I get all sort of strange ones (integers). I am already using Acct-Authentic properly working with other software on the same radius server. Here is my config: modparam("acc", "radius_extra", " Called-Station-Id=$tu; Calling-Station-Id=$fu; Canonical-URI=$tu; User-Name=$au; Sip-User-Realm=$ar; Source-IP=$si; Source-Port=$sp; Acct-Authentic=$avp(s:acct_authentic); From-Header=$hdr(from); User-Agent=$hdr(user-agent); Contact=$hdr(contact); Event=$hdr(event)") I have tried different values for the $avp(s:acct_authentic): 1, "1", RADIUS, "RADIUS", etc. and each time I got a corresponding encoded. EG: If I will set the AVP through SIP-AVP or directly inside the routing script, for acct_authentic=1 I will receive in radius Acct-Authentic = 49. Are there any developers around who have implemented radius support in ser/openser and could help me troubleshooting this issue?

Re: [OpenSER-Users] OpenSER Sending INVITE twice

by Ovidiu Sas

There is no per upstream server config. Best thing to do is upgrade to openser 1.2. Starting with this release the timer granularity has been increased. If you have a high RTT, you can increase the T1 timer: http://www.openser.org/docs/modules/1.2.x/tm#AEN168 Hope this helps, Ovidiu Sas On Dec 4, 2007 12:44 PM, Douglas Garstang <dougmig33(a)yahoo.com> wrote: > > Oh, and RTT as OpenSER determines it to where?

[OpenSER-Users] Remove header from Cancel

by Jarkko Nevala

Hello. Is it possible to remove Route: -header from Cancel requests. I have an user agent that inserts Route: -header in Cancel requests. I've already tried to get rid of it with remove_hf("Route") function, but it did not have any effect. From what I understand is, that this header is quite unnecessary in a stateful proxy, because the Cancel messages are handled hop-by-hop basis. It's just that it causes problems at the next hop proxy. I didn't even know about this problem with the UA before I started using the development version of OpenSER, the 1.2.2 version removed the Route: -header automatically before relaying Cancel forward. Thank you JN

[OpenSER-Users] how does fix_nated_register() work?

by Daniel Grotti

Hi all, I have a user behind NAT with address : sip:userA@192.168.10.210:42276. When user send REGISTER, the proxy checks if user is behind NAT. If it is, proxy makes: fix_nated_register(); force_rport(); setbflag(6). When I check what kind of address proxy has saved on LOCATION database, I see at Contact column: sip:userA@IP_NAT:42276. So proxy mantains the same Port of the user and doesn't save the NAT's IP:PORT pair. Why? In this way, in fact, proxy is not able to keep connection alive. Regards, daniel

[OpenSER-Users] Module Programming

by Daniel Corbe

Hello, Is there a better module programming guide than the one found on the docuwiki at http://www.openser.org/dokuwiki/doku.php/development:write-module ? It really doesn't explain much; for example the fact that functions are (or used to be) called with a paramater struct sip_msg *. The original SER 0.8.x and 0.9.x core had an extremely comprehensive guide to writing modules; however, I'm reluctant to use those texts as a guide for fear that the material is dated. Regards, Daniel
