We are using Asterisk and SER with Polycom 550 phones running SIP version 2.2.2.0084. The phones register to SER. If an AOR appears on more than one phone when a call arrives for that AOR one, some or all of the Polycom phones reboot. I can't seem to find the source of this problem. Has anyone else encountered this problem? Thanks,Steve -------------- next part -------------- An HTML attachment was scrubbed...
