Is this correct?
Close, but no. The way you coded the rule "10[12]" it treated as a literal, so you are checking for 6 characters, not 3. When you enclose the argument within parentheses, it becomes a DigitMap and the special characters act the way you intended.
{(10[12])>17771234567:aa}
It seems you want to learn about this device, so I'll give you some more info. These rules are for security and prevent hackers from accessing you OBi200. These hackers are called SIP Scanners and they make SIP calls to your Public IP address. You really don't need both arguments and can use the following rule, so you will accept only calls from your Callcentric account:
{>17771234567:aa}
Now any extension from your Callcentric account will be routed to the AA.
There is another way you block hackers:
Voice Services -> SP4 Service -> X_AcceptSipFromRegistrarOnly: Checked
The OBi200 firmware will block any call not from your Callcentric account.
Now you can use this rule: {aa}
