We believe there is still a major issue surrounding the VoIP proxy. Its fine if you want to only connect out to VoIP servers, but if you host your own VoIP server, and if you have multiple IP addresses, then presumably you will want to have your VoIP proxy operating on other than the default gateway. As I understand things this is not possible at this time, which prevents corporate users from taking advantage of the proxy. Whilst you can SNAT the fixed SIP ports (5060) it does not seem to be feasible to SNAT the RTP ports as they can range over 20,000 ports.

What we would like to see is the ability to have the proxy assigned to a selected IP address so that it automatically (without SNAT) provides outgoing VoIP traffic with the correct source address. Also, if we have a separate link for a dedicated VoIP link, we would like to be able to assign the proxy to that link (think leased lines and separate ADSL links).

As an aside, the ability to select an IP address or interface for all of the Astaro proxies would be welcome. Saves a lot of work!
