Hi,
I have a SBC front-ending ASTPP.
PSTN --------DiD Providers ----------Internet -------SBC = 10.10.10.1 ---"Local LAN subnet
10.10.10.0/24"---------10.10.10.2= ASTPP
--------10.10.10.3=FusionPBX
Now PSTN Inbound calls to DID assigned to ASTPP Accounts fail for IP Authentication issue.
If I set an IP Settings assigned to a DiD provider account on ASTPP all inbound PSTN calls are assigned to the Provider account. And as a consequence only the provider account is billed: Customers can receive call for free!
Could someone help on the correct solution to this issue?
Regards
William
