The error “No matching endpoint found” is usually because you set the destination device up in one channel driver (say, chan-sip) and then tried to send to registrations for that phone to the wrong TCP-IP port (say, the one for PJ-SIP). Double check your extension configuration and make sure you are registering everything in the right channel driver.
