[Asterisk-Users] ShoreTel 210 MGCP phone drops calls with MGCP RSIP

[Duane Cox]

RSIP = Restart in Progress.  This message is sent from and endpoint to the call-agent when the line is being disabled/reenabled,
and at startup.

I would think that * should tear down any active calls that is going on when a RSIP comes in, so from what I am reading this is
correct.  The bigger question is, why is your phone sending RSIP during a call?  Maybe your phone isn't 100% setup yet, but enough
to get calls up.

See if you can capture an "mgcp debug" from the * CLI.
