There are two scenarios in play here:
- You make a call directly via your ATA. VoXaLot is still sending your ATA's IP address (as it has done since we made the change a fortnight or so ago.) Nothing has changed on our side. Betamax must have changed something on their side.
- You make a call via the web-callback. In this case, VoXaLot is initiating both call legs, so Betamax will receive the VoXaLot IP address. This is a limitation of the web-callback service. Because you aren't initiating the call from your ATA, we don't know what your ATA's outward-facing IP address is, so we can't send that to Betamax. In this case, Betamax may block the calls (I suspect this is the case for web-callback).
We will contact Betamax to try to understand why the first scenario is not working as you would expect.
