NANP:PreDot vs PreDot

[Rolando Valenzuela]

Beside the obvious name what is the real difference of NANP:PreDot versus PreDot on CUCM?

I was making a couple of test and they do the same for patterns like:

9.[2-9]XXXXXX

9.011!#

555.42XX

777800.[2-9]XXXXXX

So I don't really understand the difference, and therefore I always uses PreDot but I was wondering if there's a trick/function that I'm not seeing here.

I believe this is a cosmetic difference only. I have configured route patterns that do not conform to the NANP dial plan that rely on the NANP:PreDot discard instruction at the RL/RG level and it works just the same as PreDot on the Route Pattern itself.

The only difference is that one is available at RL level while one is RP only. Apart from that the functionality is the same.

Just making sure! :)

Thank you both!

I don't believe that is true. Patterns like 9.XXXXXXX will not have the 9 removed with NANP:PreDot.
