Hi everybody, it seems some phones (Snom at least) support COLP (connected line update) in ringing phase by having the To:-header changed in the 180 ringing to a-pty. Snom have a nice detailed illustration on their wiki: http://wiki.snom.com/Category:Connected_Line_Identification_Presentation_(CO...) So if Fritz (111) calls Hans (222): INVITE sip:222@myshop From: "Fritz" <sip:111@myshop>... To: <sip:222@myshop>... The response sent to 111 should look something like this: SIP/2.0 180 Ringing From: "Fritz" <sip:111@myshop>... To: "Hans" <sip:222@myshop>... So basically i suppose i want freeswitch to stuff a effective_caller_id_name (if set) into the To: header in the a-leg, given somthing like the following dialplan snippet: <action application="export" data="effective_callee_id_number=${user_data(${dialed_extension}@${domain_name} var effective_caller_id_number)}"/> <action application="export" data="effective_callee_id_name=${user_data(${dialed_extension}@${domain_name} var effective_caller_id_name)}"/> <action application="bridge" data="user/${dialed_extension}@${domain_name}"/> Is this possible? Thanks, Markus
