| Re: NAT Support? It doesn't support NAT now, but it's very easily something others can implement:

Will EarthLink SIPshare work behind NAT?
No. All messaging, including the file transfer protocol, are based on UDP. If you want to extend EarthLink SIPshare by incorporating something like STUN for NAT traversal, by all means do so.

SIP works fine behind NAT.
This is not true. Make a google search regarding SIP and NAT issues. The NAT gateway/firewall must be SIP aware to pass through standard SIP protocol. There are currently a bunch of routers that fail SIP and they need new firmware to function.
Yes, there are efforts to add to the SIP protocol to work behind NAT gateways but not all SIP device and gateway supports this. | |

| Re: NAT Support? I disagree.
My previous job was at a SIP-based VoIP provider. We had SIP softphones on the computer as well as hardware phones.
I would say that about 99% of the time they worked just fine behind NAT w/out any configuration being done on the router.

We found it to work on plenty of old routers, etc.
