Hi,
I am facing a strange problem,
on H323Connection::OnAnswerCall i am returning AnswerCallPending.
and after sometime i call H323Connection::AnsweringCall with AnswerCallNow  .
but what happens now and then, i would say every second call, is that, even if i call H323Connection::AnsweringCall, the PDU does not seem to have been sent. the connection then proceeds to be in a vegetative state. when i disconnect the connection and reconnect it, it proceeds to connect successfully. 
i am not creating any extra threads in the system. the logic for H323Connection::AnsweringCall runs on the main thread.
i am using h323plus version 1.26.5.
regards
