[cisco-voip] 7921 reboots when second incoming call goes to voicemail

[Brian]

I have some more information regarding this.  I removed the 7921 phones as
controlled devices on the CTI application user for Unity feature services
and I am no longer able to replicate the rebooting issue.  We're wondering
if the Message Monitoring feature with Unity 5 is somehow causing this.  Is
anyone using Message Monitoring with 7921 phones?

Thanks,
Brian
