Hi,
I tried to use the pa modules to process SUBSCRIBE request from SIP user.
However, the following error message was returned when the pa module tried
to send 200 OK response:
0(19584) ERROR: t_reply: cannot send a t_reply to a message for which no
T-state has been established
0(19584) send_reply(): Error while sending 200 OK
Looks like the transaction state was missing while sending the response.
Please see the attached debug
and error message. I can't figure out the reason for that error, could
anybody help me out? Thanks!
BR,
Kevin
