Thanks for the response Alex,
The use case is for where the upstream registrar is unable to support multiple clients, and I'm seeking a way to alter the CallID so that SBC's in the path did not reject 2nd call legs.
Hence my followup question would be technically can it be done by routing the branch to self, then modify the callid, then forward on to destination? I agree that may be undesired in a conventional proxy but if it were possible it could solve a particular issue, or do any alternative solutions come to mind?
thanks
Magnus

It cannot be. Proxies are not to modify the Call-ID, ever. Why would you want to do that?

Good evening all,
Can I ask what might be a basic question, but I would like to confirm if the CallID field can be modified/mapped when branching a call ?
Thanks Magnus
