Hello,
I have setup Kamailio(v1.5) and Rtpproxy(v1.2.1) on a Centos5.4 linux
box. Kamailio's config file has been edited to include Nat and mysql
support. With Kamailio running, i started rtpproxy using
rtpproxy -l ip_addrs -s udp:127.0.0.1:7722 -a -r /var/log -F
However rtpproxy does not seem to be recording any session. I read that
the -a switch can be used to record all sessions.
Am i missing a switch/doing something wrong while invoking rtpproxy ?
Regards,
Vikram.

maybe you
must give parameter -S /path/to/spool/dir as well. See man
rtpproxy.

br0 has a static Public IPv4 address a.b.c.d, and acts as a bridge
between eth0 and eth1. Both eth0 and eth1 do not have IPv4 addresses.
The box running Asterisk also has a public IPv4 address a.b.c.e
The default config file for Kamailio Kamailo.cfg has been edited to
include Nat and mysql support. I need Kamailio to function as a proxy by
forwarding all SIP signaling information to Asterisk.
Rtpproxy is started using
rtpproxy -l a.b.c.d -s udp:127.0.0.1:7722 -r /var/log -a
-S /root/rtpproxy
then Kamailio is started to listen on 127.0.0.1:5060 and a.b.c.d:5060
I make a test call using x-lite softphone registered with Asterisk,
however rtpproxy does not seem to record the session at all. I have
checked the directory to make sure the permissions are alright.
Is there something i am missing here ?
Thanks and Regards,
Vikram.

For that you don't need a bridge interface

If your softphone is directly registered agains Asterisk, and not to your
kamailio server ... Kamailio will not handle the signaling, so it will never
instruct rtpproxy to do anything.

Yes, your network schema is totally wrong

Take into account that if kamailio does't handle the signaling, you could not

Ok, but there is no need to do a bridge interface on the proxy for having the
rest of the servers on other lan segment.

With a bridge interface you do not have different LAN segments. A bridge
bridges multiple LAN segments into a single one. Probably they want to
have some kind of security for their Asterisk server, but using a bridge
interface connects the Internet and the LAN segment transparently. Maybe
you have to teach the customer.
For separating the networks, it would be better (from security point of
view), to NOT use a bridge interface, but do the bridging on application
layer. Therefore Kamailio supports "multi-homing" and therefore rtpproxy
has a "bridge-mode".

In this setup, if you disable routing on the Kamailio server, there is
no direct connection possible between the Internet and the Asterisk
server. Only data which passed either Kamailio or rtpproxy can get from
the Internet into the LAN segment.
In this case, Kamailio+rtpproxy are working in SBC-like style.

Thanks for your reply Klaus.
With a bridge interface you do not have different LAN
segments. A bridge
bridges multiple LAN segments into a single one.
Yes I was not clear... I just meant they wanted to keep the Asterisk server on a different
segment for their reasons,
and use a bridge to the Kamailio server.
Probably they want to
have some kind of security for their Asterisk server, but using a bridge
interface connects the Internet and the LAN segment transparently. Maybe
you have to teach the customer.
Very possible. Once we have it working both ways (with/without bridge), I have a feeling
the bridge may cause enough
issues -- or not enough advantages -- and it will be easier to convince them to re-think.
For separating the networks, it would be better (from
security point of
view), to NOT use a bridge interface, but do the bridging on application
layer. Therefore Kamailio supports "multi-homing" and therefore rtpproxy
has a "bridge-mode".

In this setup, can Kamailio allow non-SIP protocols (HTTP, SSH, etc) to pass to the
Asterisk server and/or other servers?

Hi Jeff,
kamailio is only a SIP proxy, but you could use other application level
proxies (e.g. squid for http), and of course also just us normal IP routing on
the machine.

Thanks. For now we kept the bridge config in place so no problem with other protocols.
We changed the softphone
config to use the Kamailio server as outbound proxy -- it seems to be working.
