<p>Problem: Transfer scenario causes Opensips to use the wrong CSeq number to propagate an ACK.<br>
Scenario: Call is established, in-dialog pings are sent, user does a blind transfer which causes the transmission of a Re-Invite immediately followed by an Update. These requests are answered but the ACK for the Re-Invite gets propagated with the CSeq number of the Update and not with the CSeq of the correponding Re-Invite.</p>
