Here's the scenario:
I have special ring down trunks delivered to the 3300 (V8.0) via T1 E&M. No digits are being sent to me.
The trunks do not have caller ID. In the 3300 Trunk Attributes form I route the calls to a system speed dial that routes the call over SIP trunks to a non-Mitel PBX.
We've discovered a problem on the non-Mitel PBX that causes the the ringing line not to disconnect the call if the caller hangs up before the call is answered. The trunk itself is cleared.
We've traced the problem to the line not having caller ID of any type.
My question is, can anyone think of a way via SIP Peer Options or COS to force caller ID (variable preferred)? I can use the default caller ID in the SIP peer but I really need it to be unique for each of the private lines coming in. Ideally, I would be able to show the trunk label.
