Problem with NCOS?

[glarkin]

We have NCOS 1-7 setup to provide incremental levels of access to outbound calls. NCOS 1 and 2 are for local and in-state long distance, respectively. Today, for some reason, phones with an NCOS of 1 or 2 are not allowing the user to dial a local number (toll-free works fine). If I raise the NCOS level higher than 2, they can make calls that are appropriate to that level without any problems, including local calls. Before I open a ticket with our vendor, is there anything I can check on myself? I know very little about NCOS (outside of programming the NCOS level in a set) and any advice would be greatly appreciated.

Can they not dial ANY local numbers or is it one local number in particular they can't dial? do you use seven-digit dialing for local or ten-digit?

Typically, local exchanges are all set to go to one RLB (Route List Index). Within that RLB, there are 1 or more route entries (routes that callers should use for outgoing calls of that type). In the route entry, one of the prompts is FRL - facility restriction level. Typically again, that corresponds to the NCOS. So, if you change the FRL to a higher number, or change the NCOS mappings to FRL, you can have this happen. Or, it may be a setting with auth codes being required (MFRL, another prompt in the RLB) that is blocking you.
If, as coniglio asked, it is only 1 exchange (or if you are 10-digit dialing, an NPA without the 1 prefacing it), you may just have that entry to correct. Otherwise, check the RLB that local calls go out on.

Thanks for the advice guys. I figured out what had happened: The RLI in the NPA settings for our local area code (503) had been changed from 1 to 4. Once I changed the RLI back to 1 the phones with an NCOS of 1 and 2 were able to make local calls again. Thanks again,
