It would be too late for inbound in the dialplan as the channel already exists, therefore already has a uuid. Though you can change the uuid, you'd still have issues whenever a call hung up so quickly it never reached the dialplan (yes, I've seen that happen).

Outbound you may have a chance with - but I don't know if such a variable exists.

Is there a reason you can't just set it on the profile?

Hello,

Is it possible to set the equivalent of inbound-use-uuid-as-callid or outbound-use-uuid-as-callid per channel from within the dialplan?
