[Users] reading info from custom db table
by zm23 08 Aug '06

08 Aug '06

Hi, I want to store some information in a separate table in mysql database. Think of it as a second user preference table but I want to keep that information separate. What will be the best way to achieve that? So that I am able to lookup values from this additional table and use it to make routing decisions. Also, does openser provide a way to do custom sql queries. Thanks in advance for your help. -- Zahid Mehmood CUIT Network Systems

Make sure to look at the flags for nat_uac_test. They should probably be >= 19. 2) nat_uac_test only returns true if it detects nat based on your flags. Therefore, you can use logic like this: #--------REGISTER section---------------------- if (!search("^Contact:[ ]*\*") && nat_uac_test("23")) { setflag(6); fix_nated_register(); force_rport(); }; #-----INVITE SECTION-------- #(in INVITE message handler) if (nat_uac_test("23")) { setflag(6); } #--------Extra Routes-------------- route[4] { # NAT Traversal Section if (isflagset(6)) { xlog("Fixing NAT in section 4\n"); force_rport(); fix_nated_contact(); force_rtp_proxy(); } } Now you can just call route(4) BEFORE you call your other route(s). 3) I'm not sure that I really follow you on this one... P.S. - You'll also want to run RTPProxy to proxy the media streams for clients that are behind nats. -- Kristian Kielhofner

[Serusers] SER & RTPProxy
by Sebastian Gabris 08 Aug '06

08 Aug '06

Hello everybody, does anybody have a sample config - file for this scenario : (no authentication, mysql or whatever needed. SER should just relay the call) UA(privateIP) <-> (privateIP)SER(publicIP) <-> UA-(VoIP - Provider, pubicIP) I already tried the onsip configfiles and many other files :) but I still see no way to get this SER - Router working. I already tested this enviroment with siproxd and all worked well. So the problem must be with my config file. Any help would be very appreciated :-) ______________________________________________________________________ XXL-Speicher, PC-Virenschutz, Spartarife & mehr: Nur im WEB.DE Club!

[Users] Proxy authentication message to wrong port
by M D 08 Aug '06

08 Aug '06

Hi I have an OpenSER 1.1 box on a public IP running a config taken more-or-less verbatim from the iptel.org getting started examples. I have a UA behind a PIX which is translating port 5060 on the phone to port 8907 on the firewall. OpenSER is ignoring this and sending replies to INVITEs to port 5060 on the firewall. If it's likely to make any difference, the PATed IP and the IP of the OpenSER box are on the same network. 31 61.574505 193.x.x.15 -> 193.x.x.5 SIP/SDP Request: INVITE sip:5551212@193.x.x.5;user=phone, with session description 32 61.575998 193.x.x.5 -> 193.x.x.15 SIP Status: 407 Proxy Authentication Required Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: SIP Request: Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: method: <INVITE> Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: uri: < sip:5551212@193.x.x.5;user=phone> Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: version: <SIP/2.0> Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: parse_headers: flags=2 Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: Found param type 232, <branch> = <z9hG4bK4ae31c203ab6ceb>; state=16 Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: end of header reached, state=5 Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: parse_headers: Via found, flags=2 Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: parse_headers: this is the first via Aug 4 16:05:38 sip3 /usr/sbin/openser[22195]: After parse_msg...
