Ladies and gentlemen, girls and boys,

the new testing pre-release of the best SIP proxy server ever, SER, is out!=

This major pre-release, codenamed Ottendorf, includes fundamental improveme=
to the software. The improvements allow SER users to achieve significantly =
managability and reliability by better data mode, interop features, securit=
y, etc.=20
They recollect voluminous feedback we have received from iptel customers a=
nd open=20
source users. In particular, the new features include but are not limited t=
- improved data model which eliminates any possible ambiguities.
- key under-the-hood changes with impact on performance: timer subsystem
overhaul (now fast, with fine resolution, high accuracy and variability),=
TCP processing overhaul (higher scalability)
- key reliability changes: DNS cache and IP blacklisting
- key interop changes: support for STUN-bis, presence server aligned to lat=
IETF development, sanity module for early detection of invalid messages
- more management: management features are now available via XML-RPC remote=
as well as via an alternative binary protocol
- more security: ratelimit module, more check types in permissions module
- scripting features: select operator in combination with revised AVPs,
named flags and routes, more types of routes (onsend, timer, branch)
- applications: presence has been greatly updated to keep pace with=20
development in the IETF/SIMPLE (includes asynchronous subscription
authorization, extended PIDF); web interface includes many new managibili=
features (multidomain, templates and multilanguage to name some). New
scripting flexibility allows safely for features like individual ringing
timers and direct access to SIP message elements.
- new tools: Nils's script execution tree tool
and refurbished ser_ctl
see the following links for some additional details:

Accompanying software, SEMS and SERWEB have been greatly overhauled as well.
SEMS now features improved performance (single-threaded model now), service
composition via python-IVR-scripting and B2BUA, adaptive playout buffer for
better voice quality, and more. SERWEB features new multilevel administrati=
access system, multidomain support, per-domain customization, remote xml-rpc
access, multilanguage support, and more. The new command-line utility,
SER_CTL, provides also many great improvements over the previous tool.

Shortly, we have been keeping the bar high through our participation in the=
and SIPITs. SER implements latest interop changes from the IETF (STUN-bis, =
+ XCAP, to name the most important ones) and both new features and legacy f=
were extensively and successfully tested middle of October in SIPit.

Next Steps
Keep in mind, this is a pre-release for testing purposes. It is now call on
users to test the software hard and provide feedback. In the meantime, the
codebase remains frozen and we only commit patches fixing various bugs. Once
we get good confidence that Ottendorf has stabilized and is being adequately
documented, we will declare the final release. No date has been determined =
Also, we consider changing CVS to SVN.

Again, and this is very important: the final release will be as good as the
feedback we obtain for this pre-release. Please do spend your time sending=
solid feedback back to [serusers].

We keep rolling. We are still debating with our generous contributors what =
the next possible good things to work on, the topics include but are not li=
to as of now:
- documentation.
- databases are important. LDAP and BDB, DB-API revision.
- interop: identity, TLS revision
- advanced scripting (scripting engine, vars returns, AVPs)
- uncountable improvements (futex, dev/rtc, tm/refcnts, tcp fd cache, .....)

The release name Ottendorf is coming from a place in Saxonian Switzerland, =
many iptel fellows and their friends spent a weekend during this Indian sum=

This grand achievement is result of extremely many folks who did lot
of hard work. Out of folks affiliated with iptel, Andrei and Jan spent=20
immense effort on moving SER forward, with great support from Hallik
(command-line tool), Michal, Miklos, Nils, Tomas, Vaclav (presence),=20
Vlada (new STUN). In this context, I would like to thank to our company=20
for the great support. Recently, Bogdan Pintea greatly helped to make=20
the upcoming release better and more stable under sponsorship of his=20
company, iptego. transnexus provided osp support.

SEMS has been greatly improved thanks to Stefan and Raphael.
Credits for serweb go to Karel.

Same importantly, SER has been immensely benefitting of contributors,
to name in alphabetic order at least the 'top-of-the-iceberg' fellows:
Bogdan Pintea, Cesc Santa, Greg Fausak, Greger Teigre, Hendrik Scholz,=20
<>Juha Hein=E4nen, Klaus Darilion, Maxim Sobolev, Peter N=
ixon, Uli Abend.

Great support on the mailing list has been provided by Greger V. Teigre,
Java Rockx, Klaus Darilion, Zeus Ng, and more.

Simply, this list is too short and incomplete to capture all the
generous contributions that came in -- my appologies for everyone
else I have missed.

Warnings and Disclaimers
This is a TESTING version. We are encouraging people to give it intense
testing and provide us with feedback, so that we can properly assess
what it takes to declare it final. The volume and number of changes
is big, caution is advised.

All GPL warnings and disclaimers apply.

This is SER, which is not the derivate software known as openser. We=20
have no ideas of in what extent and timeline derivate projects follow
(or not) SER.


To Give it a Try
warning: this is just a 'jump-start' for black-belt users. It is not=20
a replacement for documentation or a detailed step-by-step installation
guide. It assumes knowledge of operating system, SIP, and SER.

- make sure mysql is running. In the default configuration, SER assumes it
to be running on localhost, if this does not hold, you need to change
- make sure python is installed (needed for new command-line utilities)
- Download from CVS/HEAD using instructions at
- Compile it: make include_modules=3D"mysql xmlrpc" all
- Install it the default way of your administrative privileges allow to:
make include_modules=3D"mysql xmlrpc" install
- Download command-line tool (see more documentation under*checkout*/ser/serctl/README?re=
- cvs co serctl
- Initiate database:
./scripts/mysql/ create
- Start it. Call: ser
- Begin provisioning users with the new serctl (the capital word are just p=
lace holders)
# ser_ctl domain add DOMAINNAME
# ser_ctl user add
# If you want to have Asserted Identity header for your user
# - ser_attr add uid=3DUID asserted_id=3D"PID"
# If you want to have gateway support
# - ser_db add attr_types name=3Dgw_ip rich_type=3Dstring raw_type=3D2 \
description=3D"The gateway IP for the default ser.cfg" default_flags=
# - ser_attr add global gw_ip=3DGATEWAY-IP
- more things you may wish to do:
- familiarize yourself with current ser.cfg
- send us feedback.
