DDI / DID numbers are a function of your Telco provider's routing. This includes routing public network
calls to a trunk-group in your telephone system, then sending digits to the system. Range for DDI / DID blocks
can match your pbx dialplan or not. 800 numbers may be mapped to DNIS digits which route calls once they connect
to the pbx. Providers are the best source for what numbers they route to your pbx and the ranges and mapping
for incoming toll free numbers.
These do not have to be defined in your pbx and there is no way of telling what command you may use from your pbx
admin tools to list these.
DDI / DID can be copper analog circuits, tie, or isdn t1 and e1.
If digits sent from the provider do not match your pbx dialplan, you may be able to manipulate routing using
inc-call-handling-trmt programming to adjust routing.
