by Chris Bond 14 Jul '04

14 Jul '04

Hi, I currently have the following setup and working chris(a)sip.domain.com incoming sip calls work fine. I want to be able to setup SER to forward incoming packets for chris(a)domain.com to chris(a)sip.domain.com. I've tried the following but it didn't work. route{ if (uri=~"sip:chris@domain.com") { forward(sip.domain.com, 5060); } Can anybody help? Kind Regards, Chris Bond

hello friends, mines os is-Linux i686 i686 i386 GNU/Linux ser is -ser 0.8.12-tcp_nonb (i386/linux) iam trying to find out the least configuration for the ser to run . i.e i just want to establish a seesion between two sip end points which are in public ip and the ser is also in public ip . so with my analysis i found this as the least, can any body suggest that further decrease the statements . with regrards rama kanth ser.cfg is --------------------------------------------------- ---- global configuration parameters ------------------------ debug=8 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=yes # (cmd line: -E) check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/local/lib/ser/modules/sl.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" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) # ------------------------- request routing logic ------------------- # main routing logic route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; record_route(); if (loose_route()) { t_relay(); break; }; if (uri==myself) { if (method=="REGISTER") { save("location"); break; }; if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; if (!t_relay()) { sl_reply_error(); }; } __________________________________ Do you Yahoo!?

[Serusers] Processing a 302 Redirect response
by Robert Liao 14 Jul '04

14 Jul '04

How can you configure SER to process a 302 redirect, rather then sending it back to the SIP Client? When my SIP client places a call through SER to a destination, and the destination replies with a 302 redirect, SER seems to proxy that redirect back to my SIP client. Rather then have my client send a second invite with the new "Contact" information, I would rather have SER directly send an invite to the new destination without telling my client about the 302 redirect. I thought about using the t_on_failure, as a response code >=300 will trigger a failure_route, but how do you pull the content out of the "Contact" field of the response to put into the request URI? - Robert Liao

[Serusers] doubt with serweb + radius authentication + serctl add
by varala ramakanth 14 Jul '04

14 Jul '04

hello friends, 1)i want to know what is the extra facilities which we get if we use the subscription to the ser (i.e with serctl add or serweb giveng the access to the users). i am using the free radius authentication and its working fine for me. 2)can we use the database to the free radius server rather than just appending the username , password in the file of users in free radius server. 3)can we put the inter relation betwen the radius and the subscribe table of the ser so that we need not manually enter the details into the users file as and when i need to add the users to the ser system. __________________________________ Do you Yahoo!?

Re: [Serusers] serial forking with a recursive failure_route block
by Jiri Kuthan 14 Jul '04

14 Jul '04

I did not think so much about watching URIs, rather just keeping some internal status associated with transaction in progress. A possibility would be to cascade through failure_routes: failure_route[1] { t_on_failure(2); # if this fails, try 2 ... } failure_route[2] { t_on_failure(3); # if this fails, try 3 ... } etc. Other possibilty I thought of would be route[1] { ... setflag(1); # state == 1 t_relay(); ... failure_route[1] { if (isflagset(1)) { # try 2 resetflag(1); setflag(2); break; }; if (isflagset(2)) { # try 3 resetflag(2); setflag(3); break; }; ... -jiri At 03:21 AM 7/14/2004, Michael Przybylski wrote: >I was thinking along the lines of using the textops.so search() function. > >Will that let me see what "Contact" headers have already been appended as >branches? > >Best regards, >Mike Przybylski > >On Wed, 14 Jul 2004, Jiri Kuthan wrote: > >> A possibility to keep status would be to use flags -- a poor variable >> substitute till support for variables appears. >> >> -jiri >> >> At 10:14 PM 7/13/2004, Michael Przybylski wrote: >> >Hello everyone, >> > >> > I've got a recursing failure_route block that I'm trying to use >> >for voice over IP gateway failover. >> > The recursion bit works without any problem, but I could really >> >use some hints on examining the branches appended by previous calls to the >> >failure route so that it can know when to stop. >> > >> > Here's the pseudo-code version of what I'm trying to do. >> > >> >if(examing previously appended branches shows >> > IP of last-chance gateway already there){ >> > give up; >> >} >> > >> > Any suggestions would be greatly appreciated. >> > >> >Best regards, >> >Mike Przybylski >> > >> >_______________________________________________ >> >Serusers mailing list >> >serusers(a)lists.iptel.org >> >http://lists.iptel.org/mailman/listinfo/serusers >> >> -- >> Jiri Kuthan http://iptel.org/~jiri/ >> > >_______________________________________________ >Serusers mailing list >serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Re: Serusers Digest, Vol 15, Issue 13
by Shaharyar Awan 13 Jul '04

13 Jul '04

I installed SER without authentication or my_sql support a few dyas back. When I realized that I needed to keep some call records and enable authentication, I installed SER_MYSQL. But SER doesn't automatically use the SER database for call accounting. What changes do I need to make to my ser.cfg (or any other file) to enable accounting support with database after installing SER_MYSQL? Thanks. __________________________________ Do you Yahoo!?

[Serusers] DNS SRV problem
by Mark Cerrajetto 13 Jul '04

13 Jul '04

Hello: I have a SER proxy server, and 2 SIP-to-pstn gateways (GW1, GW2). I would like to provide redundancy with SER using DNS SRV entries. The scenario is: every call must be directed to GW1, and **only** if GW1 fails, these calls must be directed to GW2. I've created these dns entries in Bind: _sip._udp.my.service.com. IN SRV 10 0 5060 gw1.service.com. _sip._udp.my.service.com. IN SRV 20 0 5060 gw2.service.com. gw1.service.com. IN A 192.168.1.1 gw2.service.com. IN A 192.168.1.2 service.com. IN A 192.168.1.10 SER receives calls to "user1(a)service.com", and after a dns srv lookup it sends the call to gw1.service.com correcly. SER configuration is: if (uri=~"user1"){ rewritehost("my.service.com"); forward(uri:host, uri:port); break; }; But, if gw1.service.com is down, SER never tries to send the calls to gw2.service.com. SER never send INVITEs to the server with priority 20. Is it a SER limitation, or is it a configuration problem? Thank you, Mark I would like to provide failover redundancy with SER
