I have a user who will be in the "field" all the time. They will be using a cell phone for all communications and therefore no desk phone. I have provided a DID and inside extension via phantom. My problem is this:
- I created a phantom extension, 2236 with a user account
- I added the mobile number to the user account
- In the phantom > Associated Extensions, I have 92000 (automatic selection) set for Outgoing Extension
- I have call routing for inbound DID # pointing to 2236
If I call from my cell to the DID, it rings and after a few goes to voice mail. The call never gets transferred/forwarded to the cell.
If I change the Outbound Extension to 92001 (backup copper lines), then call the DID, the call goes through.
If I change the Outbound Extension to 92003 (SIP trunk group), then call the DID, the call rings and after a few goes to voice mail
So apparently the call is not transferring to the SIP trunk properly. What should I look for to resolve the problem.
I have tried using 355 2236 xxxx# 359 xxx-xxxx # to forward all calls, but the call cannot be returned to the MITEL since it is forwarded. This is reasonable, but not preferred. Also, since the call works properly when using copper, I assume that the problem is resolvable.
