Hi, I am writing some code using the pjsua user agent as reference. Now, when I call an extension from my client, I use the extension number: sip:6011@192.168.0.3 when I receive a call from the same extension, and use the pjsua_call_get_info(..), the remote_info shows the id: sip:pc1@192.168.0.3 Obviously, in the asterisk extensions.conf pc1 is mapped to 6011 exten=>6011,1,Dial(SIP/pc1,20) I wonder how can I retrieve the extension number (6011 for instance) from an incoming call (for instance sip:pc1@192.168.0.1). Thank you.
