Aastra 57i CT outbound problems

I have set up an Aastra 57i CT and itworks only partially. When I try to dial out using a PSTN phone number, it says "Call Failed" on the phone. When I dial an extension, however, which is then routed to the same PSTN number, it goes through. FYI, I have no problems with incoming calls.

Can anyone help me here?

Thanks!

RE: Aastra 57i CT outbound problems

This sounds as a dial plan / call routing issue. Do you have any way to verify what dialed string is being sent to PBXes from the Aastra phone?

Can the web interface of this phone be made available, via remote access?

On a separate note, does the current firmware of the phone support any NAT traversal methods? (STUN, TURN, ICE).
