[Serusers] t_relay_to
by Stephen James 28 Mar '04

28 Mar '04

I attempted to implement the code in the example for PSTN gateway where after matching the enum in the user portion of the uri it uses t_relay_to. When I implement this I get unable to find t_relay_to in the startup of ser. It find t_relay so I know that the tm module is loaded and exists, when I do nm on the module I see the symbol t_relay_to in there as well??? # attempt handoff to PSTN if (uri=~"^sip:9[0-9]*@.*") { log("Forwarding to PSTN\n"); t_relay_to( "192.168.0.2", "5060"); break; };

[Serusers] SER Routing Script Order
by Alan Litster 28 Mar '04

28 Mar '04

Hello, I need some clarification on the order in which the routing script is written. We have multiple gateways that we trigger on various rules. Does it make any difference to the way the routing script works if the lookup occurs at the top or bottom of the script?? Our users accounts currently begin with either a 1, 7 or 8 and are of fixed length. If we add a trigger that begins with one of those digits to send it off via a gateway, you can't call that particular group of users. Would it be best to do the lookup at the begining of the routing script or add length constraints to the triggers?

[Serusers] SER & PSTN
by alireza＠panaisp.net 28 Mar '04

28 Mar '04

Hi All I installed a SER and configured it to send the calls to a PSTN gateway. then i configured a cisco gateway for sending the calls to SER.in tis scenario there is no any problem and all the things work fine. after that i replaced the cisco gateway (that originated the calls) with a windows messenger 5.0 and started the test again, but it failed with error : "You cannot have a voice conversation with 18008782897(a)panaisp.com. This person needs one or more of the following: a computer sound card, version 4.0 or later of Windows Messenger, permission from his or her network administrator." I read the debugs and saw error : "Media Type(s) Unavailable" I replaced the windows messenger with SJPHONE but this error repeated agin "session rejected: 488 Not Acceptable media" I don't know the meaning of this error. Any experience? Alireza

[Serusers] Forwarding problem INVITE messages to PSTN through a Gateway
by Adel Al-Hezmi 28 Mar '04

28 Mar '04

Hi all, SER could not forward an INVITE message originating from a SIP UA to our PSTN gateway with URL: sip:12354@ourDomain.com, but does with the URL: sip:12345@GatewayIP. The following if statement has been added into the SER config file: if(uri=~"sip:[0-9]*@.*" &&(!(src_ip==130.149.159.196))){ rewritehostport("130.149.159.196:4000"); if (!t_relay()) { sl_reply_error(); }; break; }; In this case, SER sends the message "404 Not Found" to the SIP UA. What could the problem be? Does anyone know? Thanks, Adel Al-Hezmi

[Serusers] ACC and Radius
by alireza＠panaisp.net 28 Mar '04

28 Mar '04

Hi Guys I read radius howto and download and compile all necessary files and install all of them and then recompiled SER for supporting Radius.Authentication with radius is work great but about accounting nothing happend.(I read the acc and radius howto and know that i should uncomment 2 lines on Makefile of acc module and did it)I tested radius by a H.323 gateway and it worked and loged accounting packets but when i want to log SER it does not work, here is my ser.cfg file that related to accounting: # ACCOUNTING modparam("acc", "radius_config", "/usr/local/etc/radiusclient/radiusclient.conf") modparam("acc", "service_type", 16) modparam("acc", "radius_flag", 2 ) modparam("acc", "radius_missed_flag", 3) if (method=="INVITE") { log(1, "INVITE--ALIREZA\n"); setflag(2); }; if (method=="BYE") { log(1, "BYE--ALIREZA\n"); setflag(2); }; I read acc howto and copy the configuration from that but nothing was changed, after that i changed radius_flag and service_type to defualt values (1,15)but it does not still work.I saw some logs in /var/log/message that said: " ser[5029]: INVITE--ALIREZA " it seems ser log the invite correctly (as i configured) but nothing happens on radius. Any sugesstion appreciated. Alireza

[Serusers] disconnect
by Srbislav Cvetkovic 28 Mar '04

28 Mar '04

Hi everyone, I have a little problem. My network looks like this: x-lite softphone on mac xlite-softphone on win grandstream budgetone 100 ip phone ser proxy (freebsd port build) VEGA gateway Incoming calls work great. But outgoing calls are being disconnected after 16 seconds. Now i talked to grandstream people and i have two versions of x-lite, the new version b1101 and the old one. With the old version the outgoing calls are going fine, but the new version is not working. They told me that the old version is working because it's not using the Branch ID. The new one does, so does the ip phone, hence it's not working. I did send him the trace files and everything. Now i guess my question is : is it ser's fault or vega's fault? Did anyone experience simmilar problem? I can send you the trace files if you need them. Srbo Cvetkovic | CityNet, Inc. srbo(a)city-net.com | Pittsburgh, PA voice: 412.481.5406 | fax: 412.431.1315
