Re: How multiple ATAs can be behind same NAT router?
A while back, I had Vonage and Asterisk at the same time. The Vonage PAP2 was locked down to UDP port 5060. So I configured Asterisk SIP to listen on 5070 and a different RTP range. This worked fine for all the providers I used (Telasip, Vbuzzer, FWD, Sipdiscount, Les.net, etc.) My point is that most providers don't care which ports your end is using. The SIP protocol handles all the details.
In your case if one of the ATAs is unlocked, just change the SIP port and RTP range yourself (remembering to forward those ports in your router config). Couldn't hurt to try.
If not, maybe one of the providers will change your ATA's config to use a different SIP port / RTP range. Seems reasonable to me. Give 'em a call. |
