When UA1 makes a call to UA2, both ringing. Then UA1 cancels the call, a strange log message (from ngrep) will be got below. After that UA2 will ring 3 times itself. You can see in line 718, there is a cancel method. After that, there are many Record-Route, Via in the sip CANCEL method (line 763, line 1578 and many). Does anyone know what the problem is?
