Hi,
I am running a sipp script in which sipp is receiving REGISTER, sending 200
OK, and receiving INVITE. When I am trying
to receive INVITE then sipp reports it as an unexpected message.
Can you please help on this.
The folowing Error occurs:
2007-04-26 18:05:15: Aborting call on unexpected message for Call-ID '[EMAIL
PROTECTED]': while expecting 'REGISTER', received 'INVITE sip:[EMAIL
PROTECTED]:5061 SIP/2.0
----------------
Here is the sipp script:
