asterisk users - Aug 2005 - Incompatible destination (88) Error Message. Please Help !!!

I have connected asterisk 1.0.7 with Avaya Definity via E1 with a
TE100P Digium Card.
Inbound calls are working perfectly and I dont have any problem. But
when I try to make an outgoing call with my softphone (xlite) I am
getting the following messages.

Hungup 'Zap/13-1'
Executing Dial("SIP/IZ-bc0a", "Zap/g1/3118") in new stack
Called g1/3118
Channel 0/1, span 1 got hangup
Hungup 'Zap/1-1'
No one is available to answer at this time

I have tried to use PRI debug span 1 option and I am getting a strange
error message Incompatible destination (88) Error Message. I am also
attaching the complete degub information :
