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

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 Klaus,
just to clarify - the empty branch in VIA problem was properly fixed
(according to RFC) starting with OpenSER 1.1 - in stateful mode the 200
ACK branch gets populated and also in stateless mode a unique branch is
added to VIA.
so, if the 0 branch is reported, it means is either a bug somewhere
,either there is a processing error.

bogdan

Hi Bogdan,
I have attached an html file that shows the call trace (note that the
OpenSER is 65.185.232.62:5061in the flow). I will send the log file
and openser.cfg in a separate email since it would put me over the 40K
limit.
thanks,
Tim
