Hi,

How do you dial the users? direct with the peername or something like 
exten at ipofpeer ?

i know this problem when dialing a patton ISDN ata without an extension. 
The call is established but when the T1 sip timeout fires the call gets 
disconnected. Maybe you could do some sip debugging and watch for resend 
sip messages.

best regards

steve
