Hi When ever MySQL Server (5.0.24a) on a remote machine is restarted, SER can't reconnect to the MySQL server. I see this problem has occurred before via mailing list: ERROR message : MySQL server has gone away (http://lists.iptel.org/pipermail/serusers/2006-April/027961.html) I am running debian package of SER 0.9.6-2 (ser-mysql-module 0.9.6-2) and MySQL Client 5.0.32 . I have tested that the MySQL client reconnects after server has been restarted. Is there something I'm missing that I'm still getting this problem ? Thanks --Shaun

[Serusers] Problem with sl_send_reply: I won't send a reply for ACK.

by Ricardo Martinez

Hello list. I'm facing a problem with a UAC and i was hoping that someone can give me a hand here. I have a IP Phone calling to a PSTN number through SER and then a GW. 10.0.0.243 : IP Phone 10.0.0.246 : SER SIP Proxy 10.0.0.239 : GW SIP PSTN When the call is established and the "200 - OK" message arrives from the GW to the Proxy, the proxy re-route the message back to the Client, and finally the client respond with an ACK. Here is when te problem begins, i'm not sure if the ACK is the problem or maybe is a bug with my SER box. I'm using the Getting Started ser.cfg from iptel.org. You can see the debug here: U 10.0.0.239:5060 -> 10.0.0.246:5060 SIP/2.0 200 OK. Via: SIP/2.0/UDP 10.0.0.246;branch=z9hG4bK34e7.0648f244.0.

The ACK hits the "Sanity Checks" (Max Forwards) and then breaks sending to console : "Warning: sl_send_reply: I won't send a reply for ACK!!" I was reading the RFC3261 because i'm not sure about the R-URI from this endpoint. Let me explain : RFC3261 : Section 12.1.2 The route set MUST be set to the list of URIs in the Record-Route header field from the response, taken in reverse order and preserving all URI parameters. If no Record-Route header field is present in the response, the route set MUST be set to the empty set. This route set, even if empty, overrides any pre-existing route set for future requests in this dialog. The remote target MUST be set to the URI from the Contact header field of the response. So, if this is correct the R-URI from the ACk must be set to sip:005622408196@10.0.0.239, and not the sip:0101005622408196@sipvoiss.desa.mydomain.net. Is this ok?. I think this is causing the ACK problem in my SER box. Can someone help me here? Thanks in advance. Best Regards, Ricardo Martinez.-

[Serusers] Getting 513 - Message too big for REGISTER message

by Sudhakar Patil

Hi, I am running into the attached errors. Appreciate your help. To add further clarification, looks like if (msg:len >= max_len ) { sl_send_reply("513", "Message too big"); exit; }; max_len is getting converted to 0 (zero) and hence I keep getting 513 error message. I replaced max_len with numeric values but the effect is the same in that when comp_num in route.c is called the right value is always 0 (zero).

[Users] approaching testing phase for 1.2.0

by Daniel-Constantin Mierla

Hello everybody, we are approaching the testing phase for release 1.2.0. This week is planned to be the latest before cvs freezing. Then we will take care only of bug fixing, documentation update and small tunings. By this week we should be able to fix pending issues like script variables, dns failover and black lists, timers -- most of the code being already available on public cvs. If you have something else in mind, please send a mail to devel mailing list. Cheers, Daniel
