Hello all,
Im using ser, with esteras softphone, and a couple of cisco ata186's. I
have to say I really like ser, as it is small fast, and reliable without
being over complicated.
I would like to know what other ser users and developers use for pstn
gateways? I have a openline4 card from voictronix, but there is no
software support for sip (When I bought it I thought I would use h.323).
I have looked at cisco's pstn gateway modules, but was turned off them
because of price, and lack of clear straight forward information to name
but two reasons.
Ideally what I would like to have is a solution that would support at
least 4 pstn lines (expandable to maybe 8), that would run on FreeBSD
(or at worst linux), works well with sip & ser, with high quality audio,
and minimal delays when dialing in out.
TIA,
-Emil
Hello everyone,
I am playing around with the new CVS ser 0.8.11pre28
downloaded couple days ago. I am attaching my config
script and also the output of syslog with errors. Afer
I start ser it starts forking new processes until it
crashes the box (fills up the memory).
The script is little advanced, uses jabber,pa,msilo...
Thanks for your help. You are doing great job. Can't
wait till next release.
Peter.

I've just committed into the cvs the autopinging feature useful to
keep NAT bindings alive. If possible, please test and let me know
then. Basically, everything you need to do is to recompile/reinstall
ser and all modules and add the following into your config:
modparam("nathelper", "natping_interval", N)
Where N is some non-zero interval in seconds (usually 15-30 should
be OK).
Thanks!

As speaker and exhibitor at the event, iptel.org is glad to invite you to VoN London
(http://www.pulver.com/europe2003/). We will be presenting our application architecture
for integration of SIP telephony with legacy networks and Internet services.
In the exhibition, we are located in the booth #4 (nic.at) as a part of a world-wide
ENUM trial which leverages our SIP Express Router (SER) (http://www.iptel.org/ser/).
We will be demonstrating ENUM interoperability and our SIP applications based on the
latest SER version with numerous new features (media component, ENUM support, DDM,
presence agent, NAT traversal, web applications, etc.)
On the 9th, iptel.org founder, Jiri Kuthan, will be holding a SIP tutorial (9am-6pm).
On the 10th, he will participate in an "Open Source Voice" session (2:15-3:30pm) and
share our deployment experience with audience.
See you in London. If you need to arrange a time-slot with us, drop us an e-mail.

Hi everyone,
What's happening to the function (In the latest CVS version of Ser)?:
int is_user_in(struct sip_msg* msg, char* hf, char* group);
When I use this function in the config file it returns an error.
Did it change is name?
Did it simply desapear?
What coud it be missing here?
Best Regards,
Toni

That depends...
If that is about numbers (the common case) you can designate a numbering
plan that can be shared accross the domains (prefix 1--domain 1, prefix 2 --
domain 2) -- then you will have only 1 alias table to maintain.

Typically you do not modify aliases from SER scripts on receipt of a SIP
message -- you just look them up.

Hello again ;)
I'd like forward all numerical URI to my PSTN gateway
if (uri=~"^sip:[0-9]*@gda.pl") {
forward(10.10.10.1, 5060);
};
But if I haven't numerical user in my contact i.e
<sip:2411@10.10.10.1>;q=1.00;expires=1073143945
it doesn't works.
This statement ( if (uri......) is unnecesary :(
when I will add new permament contact for numerical URI.
Do I all my numbers write statically to contact ????
What can I do when I have their a hundreds ??
Maybe should I add some config peer for my PSTN Gateway (C2600) ??
Greetings

Hi all,
SERAdmin v.02f has now been released.
SERAdmin is a GUI interface between SIP Express Router (SER) and the SER
administrator.
Visit http://seradmin.xten.net to find out more about SERAdmin and
download the latest build.
SERAdmin provides control over many SER tasks such as: start, stop,
pause, re-start, monitor, add user, edit user, etc. SERAdmin has an
intuitive look and feel.
The Xten SERAdmin Team is comprised of 2 senior engineers and 1 project
manager who are committed full-time to the development of SERAdmin.
SERAdmin is open source, is being developed to benefit all SER
administrators, and the feature set of SERAdmin will be determined by
the iptel.org SER users' group.
So please communicate with the Xten SERAdmin Team, post your comments in
the public forums, and make use of the Xten SERAdmin Team as they are
working for the SER community.

Hi folks,
I am having problems with locking in timer routine (ser 0.8.10),
particularly with the my recent addition to the nathelper - udp pinger.
This piece of code is being invoked periodically by the timer, retrieves
list of all currently registered contacts and sends short udp message to
each of them. Obviously, routine which retrieves all contacts locks each
domain before accessing it, but apparently it doesn't work as expected.
Following is the dump of debugging session:

As you can see, we are locked domain in question (line 103), but still,
found one of records to be in the inconsistent state (contacts aren't
initialized).
Does anyone have any ideas about what could be wrong with this? I an
seeing similar problem in the code that periodically expires contacts.
