[SIPForum-discussion] Solving "the delaying bye" when 200OK is not ACK-ed

Hello experts,

I use a the PJSUA library 2.2.1 in a voice server that i maintains.
I'm facing a problem of  unfreed resources, when an incoming call arrives
and the 180 response is sent, then 200OK, but this latter is not confirmed
by the pabx (the ACK is never received), causing a continuous
retransmission of 200OK, then a hangup of the call is launched by the
server, which causes the delaying BYE problem. The non confirmed dialog is
then never released and the BYE never sent. So, how to do ?

Can anyone help me please ??

Thanks a lot !
Best regards,
