Both suggestions work: If I include the effective_caller_id_number in the dialplan before bridging, or if I include {origination_caller_id_number=45161061} or [origination_caller_id_number=45161061] as a part of the first parameter after a originate command. But skipping the "set" command in the dialplan, and trying to use: <action application="bridge" data="[effective_caller_id_number=45161061]sofia/gateway/45161061/$1"/> or: <action application="bridge" data="[origination_caller_id_number=45161061]sofia/gateway/45161061/$1"/
does not work. Same thing when using curled brackets. I need to be able to pass parameters individually to each of the bridge destinations, not just for the A-number, but also for other stuff to be used for post processing of the call. An alternative would be to emulate the Asterisk chan_local by making some kind of loopback to the dialplan, using IAX or SIP, but this is a inelegant way of solving it. Jon
