Update 4/10: (BYOD sip) seems to be fixed to a certain degree. The ATA registration value needs to be set lower than 4 minutes to avoid a brief 2 second premature expiration from server. For example, an ATA registration setting of 3 minutes, shows a server expiration in vPanel of 3 minutes and 58 seconds. This allows the ATA to re-register in plenty of time before the server expiration (a 58 second cushion). As of yesterday, BYOD sip7 was still screwed up. Server registrations were prematurely expiring anywhere from 20 to 90 seconds depending upon the ATA registration settings. I have not checked sip7 today.
