I'm assuming you want to ultimately have a Audiocodes gateway, firewall and sipx, where the firewall is simply a "firewall" and all user proxy, registration, etc. happen on sipx.
All of your questions have good answers in the wiki. Before you attempt to do any of this, I strongly suggest you install version 4.2.1 from ISO and have all of the prerequisites out of the way, like DNS and registering local phones, before moving onto sip trunk with itsp's and PSTN gateways. It is really helpful to make sure your firewall is configured correctly also. sipXecs supporting "server behind nat" and "remote user" requires the firewall in front of sipxecs to be properly configured. If you don't have a compatible firewall, it will not work. The requirement is for manual outbound nat or symmetric port NAT from your vlan that sipx is on to be be s. If the outbound port from sipx was 31234 (example, for media) then the media port coming back in would also be port 31234. I have a good tutorial on pfsense if you do not have access to a firewall that will do this: See: http://blog.myitdepartment.net/?p=37 On Sat, Oct 16, 2010 at 10:34 AM, David Sharafy <[email protected]> wrote: > Hi, > > I was actually searching the web for some stuff in regards to Audiocodes > and I cam across this site... > > Can I use SipXecs as a SIP registrar? if yes, will it work if it's behind a > NAT and the client is also behind a NAT? > Yes, but the remote user must have their SIP ALG and SPI turned off on their router.
