I am using AVPs for distinctive ring preferences. I allows users to
store up to 5 phone numbers that can be assigned a custom ring. The
method below works fine but as you can see it requires 5 db queries.
There must be a better way to do this. Any ideas?

if (avp_db_load("$ruri/username", "s:ringone")) {
if (avp_check("s:ringone", "eq/$from/i")) {
append_hf("Alert-Info: Bellcore-r1\r\n");
};
};
if (avp_db_load("$ruri/username", "s:ringtwo")) {
if (avp_check("s:ringtwo", "eq/$from/i")) {
append_hf("Alert-Info: Bellcore-r2\r\n");

Hi,
I'd like to use OpenSER for routing calls to NATed gateways. I also want
to support the LCR feature. Unfortunately, the current LCR module
doesn't support NAT. I mean that the gateway IP addresses must be
defined explicitly in the "gtw" table. Now I'm looking for a way to
force OpenSer to use information from the "location" table.
I want to write a module that will have the similar functionality like
the current LCR module has but resolving procedure will be more
complicated (not based on prefix and From only). The module should build
avp list where each gateway will have symbolic user name. For example,
g1, g2 etc. The gateways will also be registered on the proxy with those
names. Then I think it will be possible to call lookup("location") after
successful call the next_gtw() from the script.
Is it feasible? Is there another way to solve my problem?
Thank you in advance,
Leonid Fainshtein
hi,
is there some way, to prefix a given uri (=~[1-9]\d*, for example)
based on the From-header field? suppose i want to extract a specific
part (the area-code) from the From-header (like in bla(a)04711.sip...),
i want to add
prefix(echo $SIP_HF_FROM | sed 's/.*\@\([^.]*\)\..*/\1/')
or something like that in my SER config, but (even with the exec-
module, which isn't at all that flexible in my opinion) there seems
to be no way to accomplish this. background is my previous mail
regarding aliases based on SIP_DOMAIN. if i could just extract that
area-code from the From-header, then i could easily prefix it to the
To-header, so i would have no problems with aliases at all.
any clues?
brgds,

Hi Lenir,
Hexa values are not supported, so set "#102#8".

I have a sip server running purely as a proxy, all it does is forward
requests onto a remote sip box.
I want to log all the requests that go through it, and use this to
create billing records, but I can't get anything out of the server.
I have setup the logging level to 8, but only get a few messages at
startup. I enabled the acc.so module, in hope of creating accounting
information that way, and also nothing.
I know this must be because all my requests are forwarded, but I
should get something surely...
Any ideas what I'm doing wrong?
debug=8 # debug level (cmd line: -dddddddddd)
fork=yes
log_stderror=no # (cmd line: -E)
check_via=no # (cmd. line: -v)
dns=no # (cmd. line: -r)
rev_dns=no # (cmd. line: -R)
fifo="/tmp/ser_fifo"
...
loadmodule "/usr/local/lib/ser/modules/acc.so"
...

# initial sanity checks -- messages with
# max_forwards==0, or excessively long requests
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
break;
};
if ( msg:len > max_len ) {
sl_send_reply("513", "Message too big");
break;
};
# record transaction using accounting module

forward (192.168.1.2, 5060 );

Hello,
OpenSER port has been committed in FreeBSD ports tree. The port will
also appear as a package in the next packages build.
There are two ways to install a port in FreeBSD. Both methods require to
update the ports tree (with cvsup or tarball). Once the port tree is
updated:
If portupgrade tool is installed just do:
portupgrade -N openser
If portupgrade is not used or you prefer the usual/old method:
cd /usr/ports/net/openser
make install clean
The port allows to select some compile options like TLS support and
database support for MySQL and/or Postgres.
Some OpenSER packages have been generated for different FreeBSD versions
(4.x, 5.x and 6.0). To install the package version just do:
pkg_add http://openser.org/pub/openser/latest/packages/FreeBSD/xxxx
where xxx is the package version you want to install. Use that URL to
know the existing packages.
When the package appears in the next official build, you will only need
to do:
pkg_add -r openser
to install the package... easy, right? ;)

Dear All,
I have just followed the ser radius instructions to configure and install ser-0.9.4 from source in my redhat 9 machine. Whenever I enable the auth_radius module by inserting the following lines in my ser.cfg
loadmodule "/usr/local/lib/ser/modules/auth_radius.so"
modparam("auth_db", "password_column", "password")
modparam("auth_radius", "radius_config", "/usr/local/etc/radiusclient-ng/radiusclient.conf")
I got the error "bad config file (3 errors)" in the process of starting ser.
But ser will start smoothly when I commented these lines.
It takes me a lot of time. Pls help me to resolve this problem.

Hi every one, i interested in making SER to send a "copy" of al the
trafic than comes to another SIP server.
I want SER to act like ever, but in adition send the messages to
another server without waitting for a response.
Sorry for my english :)
Hi,
I am trying to access
ftp://ftp.berlios.de/pub/ser/latest/
to download SER. After trying for many times also, I am not able to
reach this site
Has anybody faced this problem ? If yes, what is the solution ?
>From where to download latest SER ?
Please let me know at your earliest

Rajesh

I am having a problem with calls matching a certain pattern executing
more than one block of code. I have a block of code that looks like
if (method =~ "INVITE" && uri =~ "sip:\*12.*") { ...
do some stuff
};
and another like
if (method=="INVITE" && uri =~ "sip:1[0-9]{10}@.*"){ ...
do some stuff
};
see full block here . The problem is that whenever *12 is dialed it
executes both blocks, I thought the pattern matching is just wrong
but when a number matching the second pattern is dialed then it
doesn't execute the 1st block. Can someone please explain this
behavior to me.
