Hi Badri,

It can happen if you use sipp and you place calls (sending REGISTER before each INVITE) with the same username.
I found out that passing "-cid_str somestring-%u-%s" to sipp helps.

Hello,

does it happen to have a sample trace of the register and the reply?

The reason can be that the register request has a lower cseq that
another register processed before.

Cheers,
Daniel
