[Serusers] Serweb: cannot open write fifo
by Shidan 28 Mar '05

28 Mar '05

Hi under the serweb user_interface ( I don't get this under admin) I recieve the following error cannot open write fifo in red blod after I log in. I chmoded the /tmp/ser_fifo pipe to 666 and 777 , but neither helped and actually when I did it for both, the commands related to serctl fifo freeze and the the users are not able to log into serweb. Anyone have any pointers? ------- Shidan

[Serusers] SIP Torture Tests Using Sip Foundry SFTF
by Java Rockx 28 Mar '05

28 Mar '05

Hi All. I'm doing some validation checks against my SIP proxy (ser-0.9.1) using SFTF http://www.sipfoundry.org/sftf/ I'm seeing that some tests are making further through my ser.cfg than I'd like. For example, SFTF test case214 sends an INVITE message to SER with an invalid Content-Type header. SER replies with a 404 User Not Found, which is technically correct, since the the destination doesn't exist, but SFTF complains that SER should have returned a 415 Unsupported Media Type error instead. So my question is this; even though ser rejected the SIP message, shouldn't it have performed some checks on the message to validate things like Content-Type, R-URI, etc to make sure the message is not corrupt or invalid? If not, does it make sense to do so before letting a SIP message get too far in to my ser.cfg? I did find this article in the archives which seems to indicate that ser should [happliy] ignore things it doesn't understand - but is this safe? http://lists.iptel.org/pipermail/serusers/2004-November/013171.html Regards, Paul

RE: [Serusers] usrloc and replication

Ok, here's a kind of OT question for everyone out there. Is there any point to using db_mode 1 or 2 since t_replicate exists?

[Serusers] rtpproxy usage??
by szj 28 Mar '05

28 Mar '05

It's greate that rtpproxy support multiple stream. Thanks Maxim for his great work. Now I want to test the rtpprxy+SER, But after starting the rtpproxy, I can't find which ports the rtpproxy listens. I don't understand the arguments of rtpproxy all well. Is it a must the rtpproxy runs on machine with multiple network adapters?? How to start it with the appropriate arguments? Thanks for your kind help and advance. Best Regards. Sun Zongjun

[Serusers] When will SER send Stop message to Radius Server
by matt morris 28 Mar '05

28 Mar '05

Hello List, First, many thanks to those who replied my previous dumb questions. My SER 0.9.0 with mysql auth and radius accounting with mysql is seemingly working ok. I have a question about SER's Radius accounting, but not sure how to ask, here is my situation: I'm testing out calls between XLite (caller) and a hardware phone (callee), but for some reason the call duration is always 30 seconds longer than actual (For both cases, it's the callee who does the hang up). I tried calls between XLite and XLite and the duration would be accurate. So I ngrep-d the traffic for both scenairos, for XLite-XLite's case, the flow is the side who hangs up (say, UA1) will send the BYE to SER then SER relays the BYE to UA2. Then UA2 sends an ACK to SER and SER relays the ACK to UA1. For the XLite to HW phone's case, the phone will still send the BYE to SER and SER will relay it to XLite. However, XLite will not send an ACK to SER. And the phone sends another BYE to SER and then SER relays it to XLite -this is repeated for 5 - 6 times until finally SER will just send a 408 Request Timeout to the HW Phone. And it seems this is the time when SER sends the Stop message to the Radius server, and hence the extra 30-sec call duration. So I'm wondering if SER indeed needs the ACK for the BYE message before sending the accounting stop message to Radius? Or is my situation caused by some other reasons? Thank you in advance. _________________________________________________________________ Is your PC infected?

The documentation behind it can be found in my diploma thesis. As Jan already said it's history.

[Serusers] uac_auth module??

Have either of you seen that post in the forum asking where to find something called the "uac_auth" module? If so can you reply to that post dated 2005/3/14 ? I did some Google searching and cannot find any mention of the module. I don't think the poster is referring to the new uac module in CVS head for altering the <From> header. Regards, Paul

[Serusers] Can´t CANCEL PSTN calls when using credentials

HI I have this problem when I made a call from a registered endpoint to a PSTN number through a GW AS5350 I can´t cancel this call and destination keeps ringing until timeout occur; this happen only when I use "is_user_in" function before to forward the call. some idea??? ser.cfg<::: .... if (uri==myself) { if (method == "REGISTER") { log(1, "ANALYZING REGISTER REQUEST\n"); # to use digest authentication if (!www_authorize("mydomain.com.pe", "subscriber")) { www_challenge("mydomain.com.pe", "0"); break; }; if (!save("location")) { sl_reply_error(); }; break; }; if (method == "INVITE" && src_ip!=GW_AS5350_IP) { log(1, "ANALYZING INVITE REQUEST\n"); if (!proxy_authorize("mydomain.com.pe", "subscriber")) { proxy_challenge("mydomain.com.pe", "0"); break; } else if (is_user_in("credentials", "deactivated")) { sl_send_reply("402", "Su cuenta fue desactivada"); break; }; }; /* ***************** Dial out to Local and PSTN logic ****************** */ # forward n digit requests to gateway AS5350 (Celulares) if(uri=~"^sip:9"){ log(1," digit expression match - Celulares"); if (!is_user_in("credentials", "mobile")) { sl_send_reply("403", "No permission for mobile calls"); break; }; rewritehostport("GW_AS5350_IP:5060"); route(1); ## to NatHelper l... break; }; # Forward calls to 6607+ to Asterisk OH323 Module gk´s if(uri=~"^sip:6607[0-9][0-9][0-9]*@(mydomain\.com\.pe)"){ rewritehostport("Asterisk-IP:5060"); log(1,"digit expression match - Local (oH323)"); route(2); break; }; ..... . . . -- rrgv

[Serusers] rtpproxy logs
by SER Users 28 Mar '05

28 Mar '05

hello, how can I access/enable/find logs from rtpproxy ? I see in rtpproxy sources that logs are being generated with "rtpp_log_write", but where are there or how can I "enable" them. I am interested to see when a session is "active", when a packet from both caller/callee are received in order to track down a problem I have with 2 UAs. something else: when everything is OK how many ports should be opened for s single proxy session ? 2 (1 RTP+1 RTCP) or 4 (2RTP + 2RTCP) ? when two UAs can not come to an agreement regarding a codec, is there any RTP traffic between the two, or media negotiation is based solely on SDP messages contained within INVITE/OK SIP messages ? thanks, razvan radu
