Receive and send sip in two applications at the same time

Question

I have a softphone X-lite installed on my computer. i wanted to develop a program in C # to see the sip messages it receives and sends. already built a softphone that does this. but I want it in a standalone application. I'm in trouble because I can not use the same port for two aplications ... someone can help me?

Sorry for my bad English...

Answer 1

Try using pjsip

it is open source tool. Try and run the pjsua application. It will let you make/receive calls from any port of you choice. It will act as a UAS/UAC. You can also register your X-lite client at this port.

E.g. pjsua --local-port=5090
