Hello Ron,
Thanks for your response. Now I'm able to start and destroy dialog properly.
But I guess dialog timer is reset when openser receives "Update" message. I
looked in dialog and sst module codes and found that they rely on UA to send
"Update" message periodically to keep the dialog active. I dont think it is
good idea to rely on clients as all clients may not be sending "UPDATE"
messages after call is established. Correct me if I'm wrong. Also I think
that I may have to change source code of dialog or sst to send bye if any UA
is broken and can't send "Bye" in case of dialog timeout.
