I'm sorry I didn't read your email fully before. My BAD
Anyway the problem appears to be that you are opening 2 control channels on 2 different threads
2:26.038 H225 Calle...er:22641e8 H245 Handle control channel 2:26.038 H225 Calle...er:22641e8 H245 Start control negotiations 2:26.038 H225 Calle...er:22641e8 H245 Sending TerminalCapabilitySet: outSeq=1 2:26.038 H245:6f3ff60 H245 Started thread 2:26.038 H245:6f3ff60 H245 Handle control channel 2:26.038 H245:6f3ff60 H245 Start control negotiations
Looking at the code I cannot see how this is even possible to do? My Guess is that in you derived H323Connection::OnSendCapabilitySet() You are starting a control channel. That's not wise. If so I would remove that segment of code from your application.

After 8-10th times of placing and ending call (without restarting application) my Application crashes in ptlib in file asner.cxx at line 2079 (Below at line no.6 for your reference) Crashes are at both Local and Remote side on same line
1 PASN_Choice & PASN_Choice::operator=(const PASN_Choice & other) 2 { 3 if (&other == this) // Assigning to ourself, just do nothing. 4 return *this; 5 6 if(choice!=NULL) 7 { 8 delete choice; 9 choice = NULL; 10 } 11 12 PASN_Object::operator=(other); 13 14 numChoices = other.numChoices; 15 names = other.names; 16 namesCount = other.namesCount; 17 18 if (other.CheckCreate()) 19 choice = (PASN_Object *)other.choice->Clone(); 20 else 21 choice = NULL; 22 23 return *this; 24 }
I am using this in my Loadcapabilities function for H.263 CIF Image Size
capabilities.RemoveAll(); //called only once AddAllCapabilities(0, 0, "*"); //called only once AddAllUserInputCapabilities(0, 1); //called only once
preferenceorder.AppendString (H263_CIF); preferenceorder.AppendString(H263_QCIF); preferenceorder.AppendString(H263_4CIF); preferenceorder.AppendString(H263_16CIF); preferenceorder.AppendString(H261_CIF); preferenceorder.AppendString(H261_QCIF); SetVideoFrameSize(H323Capability::cifMPI); capabilities.Reorder(preferenceorder);
The last few lines of PTRACE are

CRASH..>>>>>>>>>>>>>>>>>>>>>>
This crash is consistent. Crashes anytime after 5th call.. Your comments are needed. Where I am going wrong.....
