[asterisk-users] Proxying from one server to another

[Dan Caescu]

I would try with a b2bua. 

Here's a good (imho) example:

 

http://www.b2bua.org/

 

As a second step to take, I would do automatic tftp/http provisioning for
the devices you have (unless you are talking about softphones). This way you
can specify whichever sip server you want for your devices.

Redirect traffic with iptables like this:

 

Host ~# iptables -t nat -I PREROUTING -d OLD_PUBLIC_IP -j DNAT --to
NEW_PUBLIC_IP

 

I'm not sure if this will work for SIP. You may need the proxy to change
info in the sip messages between server and client.

Hi All,

 

I'm trying to find a software package to do the following sip proxy work:

 

I've an A*k server A that needs to be decommissioned, from the USA, and
replaced by server B, in the UK. Both servers are on public internet IPs.

Whilst the client migration happens, I want to divert all the Register
traffic from Server A to Server B to catch any clients still left out there.

 

Unfortunately, the original Clients were configured with static IPs instead
of DNS names for the SIP Registrar, so I have to proxy Server A until all
the clients have been updated (which might be a long time).

 

Obviously A*k itself wont do this (as far as I know).  I've looked at
siproxyd and party-sip, but with no success so far.

I've also tried using IPtables to redirect at the IP level, but the public
IP ranges seem to stop me from achieving this. It works in my local-lan
testing, but not on the public servers.

 

Any ideas?

 

Thanks,

 

Adrian
