[Users] branch parameter in ACK set to zero?

In testing with OpenSER 1.2 I noticed that the branch parameter of the
Via in the ACK to 200 OK has a value of zero. This does not seem
right. From 16.6 of RFC-3261:
The proxy MUST insert a Via header field value into the copy
before the existing Via header field values. The construction
of this value follows the same guidelines of Section 220.127.116.11.
This implies that the proxy will compute its own branch
parameter, which will be globally unique for that branch, and
contain the requisite magic cookie.
