[cisco-voip] PBX-to-IPPBX calls

[Jason Burns]

Cause i = 0x80E018 - Mandatory information element missing
Cause i = 0x80E27D - Message not compatible with call state or not
implemented
Cause i = 0x82E5 - Message not compatible with call state

Those messages indicate to me that you're sending q931 messages that the far
end switch doesn't like, or that youre getting messages that you don't like.
A sure fire indication at the far end isdn switch type is not configured the
same as your local isdn switch type.

If you're set to primary-qsig, are you positive that your provider is also
set to primary-qsig?

This may not be causing the problem you reported below, but I can only fix
the problems I see error messages for, and those errors tell me your switch
type is mismatched.

For the problem with the call disconnect it would be helpful to get relevant
debugs (SIP, Q931) from each device involved.
