Re: [Sipp-users] Receivinf REGISTER and INVITE in the same sipp script

[Charles P W. <cpw...@us...>]

Ashok,

The REGISTER and INVITE will have different Call-IDs.  To make this work 
you need to use optional messages, so that either a register or an invite 
can start a new scenario.

[Sipp-users] Receivinf REGISTER and INVITE in the same sipp script






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 
'73...@st...': while expecting 'REGISTER', received 'INVITE 
sip:sipp@10.117.4.185:5061 SIP/2.0
----------------
Here is the sipp script:
