Today we had a 57i crash and reboot after using the conference application. The bad thing is that the phone channel stayed ghosted inside the conference. So i was in need to make a killall asterisk to solve the problem. This is a difficult situation an a company. I think that the last 57i firmware need some cleaning before to be fully reliable with xml scripts. We have seen as well some strange things with 57i configurations. We have some problems to set the codecs from the mac.cfg files, even after a phone factory default. This is not the first time we have seen a configuration problem. A couple years ago, we have seen problems with configuration of the interactive keyboard function from .cfg files. I hope in the near futur that FreePBX, Freeswitch and Aastra will work together to get a really reliable phone system, as asterisk has always been a source of problems for reliability and slow development. Thanks for your listening.
