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
