    Hello, I try to forward the calls from an extension to a direct sip URl.
    Into the field "forward to external number or SkypeID" I enter this : 200@ where 200 is the extension of the remote PBX
    When I receive the call, the forward start but with this error:

    16:50:34.094 [CM503016]: Call(106): Attempt to reach <sip:100@> failed. Reason: Not Acceptable HereReason Unknown
    16:50:34.094 [CM503003]: Call(106): Call to sip:10000%40sip.exeicom.co.uk@voip.eutelia.it:5060 has failed; Cause: 485 Ambiguous number; from IP:

    Seem that the format of the external URl has been changed.
    Is there a way to resolve this issue?
    Many thanks to all!

    As long as you are sending a Direct SIP Call to one (or a few) external IP's, you may try creating a new trunk group, where the destination is that IP. Set it to not register, it is simply a destination to send the digits. Then set the outbound rules to send only the extension number.

    This may require some "tweaking", and hair pulling.
