Stefan,
This is great and exciting news! You will have some test feedback from
me shortly.
thanks, that would be great.
What is the 'git' command to check out commit 90cccb3? I am
unfortunately rather unfamiliar with 'git'.
just do
$ git clone git://git.sip-router.org/sems
or if you have sems checked out already, update with
$ git pull
This will also be in 1.3 which is to be released this week, but it
would be good to have some broader testing and feedback before the
release.
Best
Stefan
Thanks,

Hello,
master 90cccb3 brings a rework of the b2bua with session timer
application, which supports UPDATE as session refresh method, and uses
normal SDP negotiation (INVITE+offer/200+answer) with last established
SDP in case re-INVITE is used as refresh method.
It turned out that the delayed SDP negotiation with empty INVITE and SDP
ping-pong introduced a lot of problems, structurally due to creating
dependencies between the two INVITE transactions on the two legs. This
intertwining was not only in the result of the transactions, but the
transactions themselves were coupled, which in the normal case works,
but leads to many problems in case there are errors (because the normal
methods built into SIP of resolving them don't work any more or can not
be used any more).
Also, the implementation of SST support in the B2B was greatly
simplified. Now, b2b apps can simply enable session timers for the call
legs, and everything is handled in the b2b implementation in the core.
Feedback is much appreciated!
Regards
Stefan
