We're running FreeSwitch as part of a teleconferencing service, inside a telcom (so no internet latency/NAT issues) and using g.729 We are receiving some complaints of dropped calls, including from landlines. This means they join the conference, and x minutes in they simply drop. I know that cellphones tend to drop calls frequently, but landlines are pretty reliable, and we're hearing it a lot. From the FreeSwitch side of things, it just looks like those callers hung up (but then dialed back in just a moment later). I'm attaching two different snippets of the FS log files where these issues are occurring. Does anyone have any recommendations about how to troubleshoot this? Any known issues/patches in FS that could be biting us? Is there some SIP logging we can do to debug? Are there any paid contractors avail who would have the expertise to look into this? Any help appreciated ... this is a major issue for us! Thanks much, -Dale daletrub@gmail.com
