Hi, I tried it with both ptlib version 2.12.8 and 2.12.9
and what about this statement line number 6763. if (roundTripDelayTimer > 0 && !roundTripDelayTimer.IsRunning()) {
roundTripDelayTimer is not initialized any where else in h323.cxx, it also a protected member of H323Connection, so guessing is not set anywhere else.

What version of PTLIB are you using?
I checked in a fix to the CVS to call SetInterval() instead of casting.

Hi,
I was able to solve that issue by type casting 'roundTripDelayRate' to int64_t at h323.cxx:6764 . PInt64 supports type casting.
i have a serious doubt about the code though ,
in this code starting at line 6758
void H323Connection::MonitorCallStatus()
{
if (!Lock())
return;if (roundTripDelayTimer > 0 && !roundTripDelayTimer.IsRunning()) {
roundTripDelayTimer = roundTripDelayRate; StartRoundTripDelay();}
the 'roundTripDelayTimer' is never initialized any where in the code. it is also a protected member of the class,as such the condition in the if block may never be entered.
so going by previous definiton at v1.26.3
where the code is
void H323Connection::MonitorCallStatus()
{
if (!Lock())
return;if (endpoint.GetRoundTripDelayRate() > 0 && !roundTripDelayTimer.IsRunning()) {
roundTripDelayTimer = endpoint.GetRoundTripDelayRate(); StartRoundTripDelay();}
shouldn't the code be like this .
void H323Connection::MonitorCallStatus()
{
if (!Lock())
return;if (roundTripDelayRate > 0 && !roundTripDelayTimer.IsRunning()) {
roundTripDelayTimer = ((int64_t)roundTripDelayRate); StartRoundTripDelay();}

Hi Ankur,
thanks for the bug report.
I've replaces the Assert with a null pointer check to avoid the crash. Please try the CVS.
