Hello all, I am using pjsua to build an instant messanger. I have only one computer to test it. I have build two UA with IM capabilities. The first account has the URI: sip:sip1 at 127.0.0.1:5060 The second account has the URI: sip:sip2 at 127.0.0.1:5061 I have registered the callback of instant messaging with the first UA where the arriving IM will simply be displayed in the screen.With the second UA, i send the instant messages. The problem is that i cannot receive the instant messages with the second UA. Is this problem caused by the port used? (When i have used the same port 5060 for the 2 UA's there was a problem because this port must be used only by one account). Please help. Best regards.
