Summary:                    E1 PRI channel 'glare', where asterisk hangups up
the inbound call from network.
Description: 
randomly we are experiencing an ISDN 'glare'.

Captures caught so far have been our IVR dialing back out to the PSTN, at
exactly the same time an incoming network call arrives.

The issue is, asterisk hangs up on the inbound call from the network, that
has the channel set to exclusive, where the outbound call has only
requested a preferred channel, which later is assigned to another channel
in the SETUP ACKNOLEDGE.

Looks like we have outbound precedence in a 'glare' situation, when really
the inbound call is probably more important.
