Yeh, in the outbound route you can change the:
effective_caller_id_number=${outbound_caller_id_number}
to:
effective_caller_id_number=01234555555
A lot of SIP trunk providers will typically normalise the CLI if not correctly formatted (usually to the trunk authentication number) but some don't and just reject it. It really is a wild west out there with SIP.
