When I set an extension to "ring my mobile simultaneously", calls from internal extensions are rejected by my SIP trunk because the caller ID is not E.164 (it caller's extension as the user part i(.e. sip:[email protected]). I can fix this by changing the outbound parameters of the trunk from OriginatorCallerID to OutboundCallerID which uses the main caller ID of the trunk, but then I lose the ability to send the caller ID of external calls to the target mobile number. I think the right solution to use the "Reformat Outgoing Caller" feature of the trunk but I cannot get the standard regex expression [0-9][0-9] to work. This expression should match only extensions from 00-99. Does this feature use standard regex expressions? Otherwise how can I reformat the outgoing caller ID for only internal extensions for the ring my mobile simultaneously feature?
