Forward calls to direct sip URl

[exeicom]

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 : [email protected] where 200 is the extension of the remote PBX 123.123.123.123.
When I receive the call, the forward start but with this error:

16:50:34.094 [CM503016]: Call(106): Attempt to reach <sip:[email protected]:5060> failed. Reason: Not Acceptable HereReason Unknown

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.
