I am running Asterisk 13 with PJSIP channel driver and need to connect it to VoIP provider which requires a custom registration string on a SIP trunk.
Setting a custom registration string in chan_sip driver was quite straightforward by using “register” directive in sip.conf file. However, it is not that straightforward in chan_pjsip.
- Are custom registration strings supported in chan_pjsip?
- Are client_uri and server_uri parameters in [register] section the right places for customizing registration string?
- Are there any syntax guidelines for these parameters? Which of them (or both) should be manipulated to get a custom string?
Thank you in advance.
