[asterisk-users] Proxying from one server to another

Re: [asterisk-users] Proxying from one server to another
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. --Dave From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Adrian Marsh Sent: Wednesday, May 13, 2009 8:55 AM To: asterisk-users@lists.digium.com Subject: [asterisk-users] Proxying from one server to another 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.

Re: [asterisk-users] Proxying from one server to another
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.

Re: [asterisk-users] Proxying from one server to another
Hi David, Thanks for the reply. That's pretty much what I've already tried, but with no luck on the production machines. In testing it worked, but the public IPs and single NICs were causing issues (we believe) So I was looking for a proxy-type solution.

Re: [asterisk-users] Proxying from one server to another
Why not use OpenSIPS or Kamailio in stateful mode? You will need to look at how media is handled though, but a SIP proxy will work easily.
