We have two MCD installs: one MXe and one VMCD, both running 7.0 PR1. We use SIP trunking with two MBG units running V8.0.27.0. Both MBG units are configured for both MCDs. During a recent power disruption that lasted 10 minutes*, phones failed over from the MXe to the VMCD as expected, but incoming calls received dead air. Outgoing calls were fine. How should I go about troubleshooting this?
*By the way, I expected that having two power supplies would maintain service during the replacement of one power supply (this is mentioned in the documentation). However, when power is lost to one power supply, the unit reboots when power is restored. Has anyone else seen this? Is this a feature of the platform, or do I have a faulty unit?
