I’m trying to perform a SendEvent SMS::MESSAGE via ESL and have the MESSAGE go to a different URI than the “to” or “full_to” header that is set using AddHeader on the ESL event.

Is it possible to set maybe a “sip_message_req_uri” akin to a “sip_invite_req_uri” variable or something similar for each MESSAGE?

Looking at the FS source code it seems that “to” or “full_to” is always used…

Thanks,

John
