SPA2102 doesn't increment CSeq for re-INVITES

Here is what happens and what don't:

SPA sends INVITE to UserB (lets say) 101

UserB sends OK with CSeq 101

UserB sends re-Invite with CSeq (lets say) 1

SPA sends OK with CSeq 1

UserB sends another re-INVITE with CSeq 2

SPA sends an OK with CSeq 1.

The remote sequence number doesn't change after the second re-INVITE.

See rfc3261 section 12.
