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.
Have I got it wrong, is it the ATA that makes the connection in VoIP?
