We are about to begin work on a 911 module specifically tailored to
interop with Intrado's 911 service.
I am curious if there is anyone out there that has either completed
such a module, or might have some code already written to which we
could collaborate on to get the finished product.
Thanks,

Hi Iqbal, Jan,
I changed my log to /tmp/fifo in my ser.cfg and the serctl.dat file.
I then tried adding an alias:
Serctl alias add 7890 sip:aisling@x.x.x.x
Again I got the 404 flags expected error and I checked the /tmp/fifo
file. It was empty.
I then did /opt/ser/sbin/serctl fifo ul_add aliases aisling(a)x.x.x.x 7890
0 1.00 0 128. (It would work unless I added those 4 parameters) It said
200 Added to table and the following appeared in my new log file:
:ul_add:ser_receiver_28642
aliases
aisling(a)x.x.x.x
7890
However while this said added above. When I dialed 7890 to reach the
aisling(a)x.x.x.x client, a 404 was sent to my phone.
Many Thanks,
Aisling.

Hi,
I need some advices about a design issue. I'm trying to figure out how to
manage my presence information notifications, using RFC 3856.
I have a situation in which end-to-end presence management wouldn't be
suitable.
Still I'm wondering if server based presence management is a good idea. My
thought is that it present a scalability issue.
The point is that having the presence server would have to handle every
single SUBSCRIBE & PUBLISH request then sends NOTIFY to every watchers.
Is it an efficient way to handle presence in a network with hundreds online
users, everyone having tens of contact on their list.
Thank you for your comments

We have a SER 0.9.4-rc3 (i386/linux)) system running on RedHat ES4 that
crashes about once every three days. I've done a cvs update, performed a
re-make
of all modules as well as just mysql.so and reinitialized the mysql
database using the
script provided. Nothing seems to fix the problem. Using gdb to examine
a core
dump seems to indicate SER fails when receiving REGISTER messages but I
cannot
figure out why. In each of the three core dumps the REGISTER message is
from a
different client.
Below is the gdb output from the latest core dump. Can anyone shed
some light
on what might be happening?
Thanks,Steve

Hi
Will this detect IP address also in the domain table, I have moved part
of my setup to domain and IP mode, to support quintum boxes, but the
call is failing on when I check
else if (!is_from_local() && !is_uri_host_local()) {
sl_send_reply("403", "Please register to use our service");
break;
in my setup.
The from part is not local, hence the is_from_local will fail, the
is_uri_host_local should work since the RURI contains the Ip address of
my proxy, normally it would contain the FQDN.

Guys,
Anybody has a good and detailed SEMS+SER howto, could please
share it with me. I'm making SEMS as a voicemail for SER. I'm having a
hard time configuring it. Or if not SEMS + SER maybe Asterisk + SER.
Thanks,

I've tried without success to get the PA module working properly. I did ask
questions on the serusers list bit no one ever responded.
I had a bit more luck with the internet2 PA code. I get the feeling they are
the only folks working on the PA module.
Even that code does not work as one would expect - NOTIFYs are not sent out
to reflect changes in the location database.
It would appear much work needs doing in this area.

I'd like to ask to somebody with more knowledge of me if a possible
solution to NAT traversal is really feasible.
For various reasons, we DON'T want to use an RTP proxy.
We'd like to avoid the use of STUN because: 1) creates hairpin problems;
2) many UAC have a bad STUN client code implementation; 3) it requires
additional configuration by the final user.
It seems to me that with the nathelper's message rewriting functions it
is possible to solve every problem for the SIP protocol.
Moreover, as we have the REAL IP of the UA (in the original SIP
messages) we could also avoid haipin problems: it is sufficient to use
the original IP/Port of the two UAs if both have the same natted IP (ie
they are behind the same NAT). This doesn't work when the UAs are behind
multiple NATs, but this is a relatively uncommon case.
So, the unresolved problem is with the RTP data, because we don't know
what will be the NATted port so we cannot correctly mangle the SDP data
in the INVITE message.
Am I correct up to this point?
Now, I'm asking myself if it is feasible to use a "MINI RTP Proxy" that
receives the initial INVITEs, discovering the NATted RTP ports, and then
IMMEDIATLY RE-INVITE the two UAs to connect directly each other. So only
the first RTP packet is actually proxed, all subsequent traffic will be
directly between the two UAs.
I think that something similar is done by Asterisk.
Is this feasible?
If it is, then we could have a good solution to NAT Traversal:
1) No Hairpin problems (for one NAT cases)
2) No problems of the normal RTP proxy (waste of bandwidth, longer
delays, bad scalability).
3) Will work with all type of NATs except for symmetric ones (the same
that work with STUN).
4) Simpler UAC configuraton: only username, password and sip server.
Thanks.
