said by bbs2012:Or will that happen automatically since the ATA has not registered with the FPL server?
That will happen automatically if the ATA is not registered - unless your firewall is insecure and you receive scanning calls; post back and we can give you some advice if that happens.
said by bbs2012:Is there a way to design the digit map so that 911 calls go out through SP1 and all other calls through SP2?
That we can definitely do. Please try to add the following to the beginning of your PHONE Port OutboundCallRoute:
{([589]11):sp1},
The above is from memory. To test to see if I'm right, dial 511 or 811, and if the call is routed via VoIP.ms, 911 should work properly.
said by bbs2012:And one more question - is there a way to automatically block caller id for outgoing calls using the digit map? (since FPL does not allow caller id spoofing)
As far as I'm aware you can't do this, but you could try to dial *67 before a call to test to see if I'm right.
