INVITE Parse Failure using Linphone #7

Closed kingster closed 4 years ago

kingster commented 4 years ago

Hi

I have an invite which causes b2bua to crash the sip call

Error Info

2019-12-26 07:12:50+00 ERROR: UasStateIdle::RecvRequest: #1: ParseSipAddress #1"

I did a little debugging and found that ParseSipAddress function gets input lime", which means something breaks in the Contact line.

The sip-client this happens is with LinPhone
