Hello All,

I have an issue of handling Invalid Rseq value in 180-Reliable Response of
INVITE.

According to rfc 3262

The value of the header field for the first reliable
provisional response in a transaction MUST be between 1 and 2**31 - 1.

My question is what should be the behaviour of client ( UAC) if it recieves
an 180-Response with Rseq Value more than 2**31 - 1 ?

Regards
Sunil
