[asterisk-users] need to be able to pass a call to the pstn from another pbx trunk

[Jared Terrell]

pstn                                                           pstn

asterisk                 link between                 avaya pbx

both systems tied together by 2 pri's
both have trunks out to the pstn
want to get rid of the avaya pstn trunk and send thru my asterisk box
avaya still has inbound calls on this trunk until late november (at&t
is dragging their feet doing the porting - 8 weeks between ) and still
has stations that we are not in a position to migrate to asterisk just
yet (about 500)
can get the call to show on the link between systems, but asterisk has
no station associate it with so it drops?
any suggestions out there?
