Suggestion: Echo Test Callback
Most people use the *600 echo test when they first setup a system.
But to test incoming calls you usually need a friend to keep calling you or use one of the PSTN gateways to call your SIP number. For those who are not in a city with a local PSTN gateway this can get expensive.
Can I suggest that voxalot have another number (eg *700) where you can call, hangup and then ten seconds later, voxalot will call your number back and initiate the echo test, so you can check the incoming audio.
