[Sipp-users] Discarding message which can't be mapped to a known SIPp call?

[Bharath M. <Bha...@Su...>]

I am doing some testing which requires to run sipp in two mode, one with 
INVITE and another with INFO. First, I run INVITE of 1000 calls with one 
sipp process and for the same 1000 calls i run another sipp for INFO 
using injection file. All works fine except that sipp complains about 
200 OK for INFO with the following message.
 
Discarding message which can't be mapped to a known SIPp call.

But if i trace the tcp messages, sipp is indeed receiving the 200 OK for 
INFO from the server.

Here is the output at the sipp side:

                                            Messages  Retrans   
Timeout   Unexpected-Msg
INFO ---------->  B-RTD1      1         0
200 <----------  E-RTD1          0         0         0         0


Now, my questions are

1. What is identified as a call in sipp? Is it call-id, to-tag, from-tag 
or something else?
2. If i just have a send INFO and recv 200 OK messages in the xml, will 
this work as expected in sipp? Techincally, INFO is sent with in a 
dialog right.

Thanks in advance,
