How to make call between two pjsip applications locally?

Question

I'm new to SIP and I'm using pjsip as my stack.

I've successfully built pjsua on Windows. I can make call to another pjsua instance, with the help of a SIP server.

Is there a way to run 2 pjsua instances locally, or in LAN, and WITHOUT any SIP server (registra, proxy, ...) and allow to make call between them ?

Guess you might have got answer, might help anyone who comes across this page.

yes, it is possible. Start 2 instances of pjsua on 2 different ports. Try "--local-port" option. Call from 1st to 2nd by implicitly specifying the port "sip:178237@192.168.10.10:5090". Each instance will act as uas for incall and uac for outcall
