I'm running sipXconfig (4.2.1-018971 2010-08-17T02:20:18 build20), sipxbridge, Verixon VOIP, Polycom 450s, 550s, and 1 650.
It has been a rough week. I'll leave out some of the details as to how I got where I am, and just describe the problem. I have sipxbridge set to allow all codecs. Phones are set to use G722, G729, and G711 in that order. The goal is to have G722 for internal communication and G729 for calls to the PSTN. Verizon does not allow G722. They do support codec renegotiation during a call. I'm having a variety of problems that I believe may have something to do with freeswitch (within sipx) not supporting G729. I have different symptoms with different firmware. 3.1.3c - Call drops when performing a blind transfer - destination phone rings one time. Hold works fine. 3.2.1b - Call cannot be retrieved from hold. Transfers do work. 3.2.4 - Call drops when performing a blind transfer - destination phone rings one time. Hold works fine. If I put the defaults back in sipxbridge to block G729, everything seems fine. I upgraded to 4.2.1 from 4.0.4 a few months ago. We were going over our allotted bandwidth and dropping calls. That was when I realized the new default setting in sipxbridge blocked G729. We need to use G729, so I blanked out that field. I'm guessing that is when the things above started going wrong. I have no idea why the different firmwares behave differently. I'm running 3.2.1b right now with unhappy users. I've got an urgent request in to Verizon to up our bandwidth on this circuit, but that can't be my long term solution. I will be glad to provide wireshark or merged logs for any of these scenarios. I tried sipx-trace, but I wasn't able to get a lot of info. I have it on an isolated system, so the logs aren't full of unrelated stuff. I've read through this: http://wiki.sipfoundry.org/display/sipXecs/G729 and I have looked at some of the posts in the past few months about G729. Would you assume this is a G729 issue? From what I've read, it doesn't look like I have any options for licensing G729 for freeswitch on sipx 4.2.1. My brain is just about scrambled eggs right now. I'm really looking for: 1) basic thoughts on my issue if anyone can enlighten me 2) a possible fix related to firmwares, in case there is something along those lines that would help me 3) long term solution for licensing g729 in freeswitch (assuming I am correct in what the issue is) Thanks as always, Matthew _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
