Hi Tim,
the VIA branch param must not be 0, indeed. Could you provide an network
trace for the entire call and the debug log for level 9?

Hi,
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 8.1.1.7.
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.
Please advise.
thanks,
Tim
