Hi,
I have a simple application where I am trying to an SRV record to load
balance towards a few different destination servers.
I set up my DNS server to resolve to four different destination A
record URIs - something like:
_sip._udp.aimcidfilter.com 180 IN SRV 1 50 5061 crunch.com.
_sip._udp.aimcidfilter.com 180 IN SRV 1 50 5061 spinner.com.
_sip._udp.aimcidfilter.com 180 IN SRV 2 50 5061 homer.com.
_sip._udp.aimcidfilter.com 180 IN SRV 2 50 5061 bart.com.
In my configuration file, I am putting a domain name in my call to
seturi as follows:
seturi("sip:feature_fs@aimcidfilter.com:6010");
and then I call route to send the INVITE.
I was expecting to see a NAPTR and SRV record attempts, but when I
sniffed DNS, I only saw A record attempts.
Any advice would be very helpful.
thanks,
Tim

Hi,
I am from Bangladesh. I have downloaded and configured SER for proxy
purpose.
My server is working fine in test mode. Now I need some more features using
SER.
I wants to implement CDR and credit control module with this. My OS is
Redhat Ent 4.
What are the applications I need to to do so, pls let me know.

I'm trying to compile the trunk version.
After updating I run
make distclean
and
make exclude_modules="auth_diameter h350 ldap mi_xmlrpc osp
postgres unixodbc" modules install
but after I always get:
make[1]: Leaving directory
`/usr/local/src/VoIP/openser/openser/trunk/modules/auth_db'
make: *** [modules] Error 2
What is this "Error 2" ? In this same machine I can compile, without a
glance, branche 1.2 with this same 'make' command.
Thanks for any help....

Ok, I am brand new to openser and don't really have ti routing anything
yet. But I did have a dumb or at least naive question.
Can openser be configured as a very simple load balancer and redirect
registration requests, in a round robin manner, to a set of Asterisk
servers? I know having openser be the registrar is the best solution in
the long run, but this may solve an issue quickly. I looked at the
dispatch module and I know it will do want I want for invites, but
didn't know if registration requests could be redirected.
Thanks,

Hi all, i'm newbie in SER,
I want to route RTP packets between 2
computers with x-lite client voip
in the same network through
Mediaproxy. I know this may have
no sense, but it's just a test
configuration.
The call use_media_proxy() seems to have no effect,
the
RTP packets go directly from one computer to
another, no packet trough
Mediaproxy.
This is my environment:
SER and Mediaproxy on the same PC
(192.168.123.186)
X-lite client_A running on 192.168.123.10
X-lite
client_B running on 192.168.123.168
Client_A call Client_B that accept,
but mediaproxy refuses to
proxy the call.
This is my ser.cfg

Hi,
All how can i run rtpproxy to save recorded conversation locally?
i tried:
/usr/local/bin/rtpproxy -l 1.2.3.4 -s udp:1.2.3.4:17000 -r /var/media
but got nothing under /var/media after making calls
/usr/local/bin/rtpproxy -l 1.2.3.4 -s udp:1.2.3.4:17000 -r /var/media -S
/var/media
also got nothing? has anyone tried it?
thank you

nhadie
klaus,
if you want to support domains in route headers, then you need to do
naptr and srv lookups for the domain when handling loose routing. it is
not enough to compare the domain to the ones domain module knows about.
domain in route header may namely be anything as long as it resolves to
your proxy. for this reason, i don't like the idea of domains in route
headers. it hurts performance far too much.

Hello,
I'm trying to make outbound proxy for my network using OpenSER.
Currently I've configured OpenSER as sip registrar/rtpproxy and it works
fine even with NAT traversal. The problem is that I don't how shuould I
reconfigure my config to make it work as outbound proxy. I've tried many
changes with no results. The first problem is how to correctly handle
the register method. My config is based on:
http://siprouter.onsip.org/doc/gettingstarted/ch08s02.html
Can anyone help me?
Best regards,
Dawid Jaroslawski
Hi everyone,
I use 1.1.1 notls,
in my testing environment I came across some strange errors when using a
home made script in combination with the openserunix util.
First of all there were thousands of files like"/tmp/OpenSER.XXXXXX"
but looking around with google I found a patch for that:
https://sourceforge.net/tracker/?func=detail&atid=743022&aid=1708301&group_…
Then with the home made script I was still getting lots of socket
errors in syslog, a colleague of mine fixed the openserunix.c

maybe this is useful for someone since even the newest OpenSER version hast the "buggy" openserunix util :-)
