Hello Stephen,
The call is discarded because the Call-ID contained in the INVITE received by B
does not match the Call-ID contained in the REGISTER sent by B. Therefore, B
does not recognize the incoming INVITE as being part of an existing sipp dialog.
The workaround for this use case is to use two sipp instances to emulate B: one
for registering and the other for waiting incoming calls from A.
Regards,
Olivier Boulkroune

Objet : [Sipp-users] SIPp discarding msgs meant for itself.
Greetings SIPp Listers,
I am trying to get a simple A calls B call to work with SIP server "Vocal."
Both endpoints are instances of SIPp.
The call flow is as follows:
B registers and waits for an invite from A
A registers and sends an invite to B
At this point Vocal forwards the invite from A to B and the instance of SIPp
representing B discards the incoming invite.

The question: Why does SIPp disregard a message meant for itself?
I would assume that a SIP message on the port that the instance of SIPp is tied
to would be received and not discarded.
Thanks,
Steve
