You could also setup a "Facility Access trunk test" to dial out a specific trunk member.
Setup the Feature Access Code (change feature access code - usually on page 2)
Enable the COR of the trunk for facility access trunk test (change cor xx ) and the Cor of the station you are using...
dial the FAC, then for the letter "a" use 1, "b" use 2 etc...
So trying dial dial out port 02a1101 of trunk xx you would dial *xx (fac code)then 0211101, you'd get dial tone, then dial the number you wish to dial... (no 9 for an outside line as you are already on an outside line)
Thanks,
