Add sip header information with freepbx


Is it possible to add sip header information in outbound routes with freepbx.
I want to add the “Remote-Party-Id” line to the sipheader. with a pure asterisk installation I do this with SIPAddHeader() in extensions.conf.

I need this because with this way I can change my outgoing callerid number of my sip trunk. there is the extension option outbound CID in freepbx but with this options, this does not work.

is this possible somehow?

thanks for help


add to your trunk configuration:


then Asterisk will take care of it and the normal FreePBX CID control should work fine.
