Blocked area codes

We have recently discovered that our Meridian1 PBX doesn't permit dialing area code 731, which I believe is a new area code for Tennessee.

I'm still fairly new to switch programming. How can I add or unrestrict this area code in our system?

RE: Blocked area codes

Sounds like you are missing the area code.  Try this:

First print out an existing area code to find the RLI
ld 90
req prt
cust 0
feat net
tran ac1
type npa
npa xxxx (choose a known TN area code)

make note of RLI

req new
cust 0
feat net
tran ac1
type npa
npa 1731
rli xx (number from above)

hope that helps.

RE: Blocked area codes

Additionally, you may be interested in this site which list all current in use mandatory, voluntary area codes and programmed splits.  A lot of good information here including individual CO prefixes (NXX's)


I check it periodically to determine what, if any changes, will be required to my NPA and NAA tables.
