Here's the scenario: Customer has SIP trunks with DIDs from many, many, many different area codes from across the US. They want to be able to tag an outbound call with the local number they own based on the area code they are dialing. For example, if they were to dial [9]1-717-xxx-xxxx, based on the 1st few digits they dial, it would route to a matching ARS pattern and tag with the appropriate outpulsed caller ID (NSI717xxxxxxx). The other question is if this can be accomplished with SIP trunks or do I need PRI/ISDN to manipulate CID with ARS? Hope this helps...
I have a customer that has a metro calling scope one a PRI at one of their locations and wanted to send certain prefixes in certain area codes to that PRI. So because of the limit I created a different ARS table for each area code and then populated the prefixes that were included. It was a nightmare and took me days to get done, and you better believe I have it backed up but it works just fine.
