Does anyone use TekSavvy's VoIp?
Hi, TekSavvy supports VoIP by selling you an Analog Telephone Adapter (ATA). I'm figuring out how to open a open holes in my firewall to connect it to TekSavvy's server. I've asked them what subnet their servers are in so I can restrict traffic from the ATA to it. But the TekSavvy techs seem really confused by the question. Have I got it wrong, is it the ATA that makes the connection in VoIP? -- Michael Galea

I did set the ATA as "max priority" in router QoS page, just in case. But, nothing to firewall. Flip side of such convenience is, ATA is locked to Teksavvy. I can't login as "admin" to re-configure for VoIP.ms, even after "user" and "full" factory resets.
I've asked them what subnet their servers are in so I can restrict traffic from the ATA to it. That's outgoing traffic, no? If you really want to set it, I think voip uses standard port ranges. Look at ATA's webpage.
But the TekSavvy techs seem really confused by the question. So, am I.

The ATA is what converts an analog phone to VoIP. As for those support techs, they might not know what subnet the servers are in. However, you can watch with something like Wireshark to see what's actually happening. BTW, I have set up a lot of VoIP phones in my work and what I worried about was the server address, not the server's subnet.

From looking at your and Williams response it seems like the ATA makes the connection to the server. I assumed that TekSavvy would host redundant servers and make incoming connections to the ATA. -- Michael Galea
