All -
Our entire system was swapped out and all the sudden our Polycom 7000 SIP devices are not working. The people who did the work said they tested and that they worked so they aren't offering support. The phones get a dial tone, call and connect but disconnect at exactly 1 minute every single time. I checked all firewall settings, checked in the Polycom config files and do not see any setting that may cause this. Internally, ext to ext (Polycom devices) also disconnect at 60 seconds. I feel like it's a Mitel setting somewhere but don't know where to look. Does anyone have any ideas?
Thanks for your time,
Bobby
