Prerequisites:

• Unable to place a call on a PRI E1/T1 line
• Calls are rejected with 'unknown number' error on a PRI E1/T1 line
• My caller id is not displayed
• My Telco/operator says that my TON / NPI is wrong and should be E.164 or unknown

Prerequisites:

• Asterisk/Callweaver with a PRI line configured and running
  

Summary :

In this article You will learn how setup Your pbx to use proper Type Of Number (TON) and Numbering Plan (NPI)

In short, You all You probably need to do to fix the problem is set two variables in zapata.conf fie, pridialplan and prilocaldialplan from default national/E.164 for both of them to unknown/unknown

Detailed instructions :

Both pridialplan (called number) and prilocaldialplan (calling number) can be set to unknown, local, private, national, and international but only two combinations are popular.

Consider the folliwing entries in zapata.conf:

pridialplan = unknown
prilocaldialplan = unknown

Above configuration sets both TON and NPI to unknown for both called and calling party identification numbers which solves most of the problems.

Another popular combo might be pridialplan set to 'dynamic' which will choose either national or international for the value depending on the dialed number, provided You setup internationaprefix and nationalprefix right.

Some telcos might require You setup TON to unknown and NPI to 'isdn-telephony/E.164' which is not supported by Asterisk . In this case You either convince the Telco to let You use unknown/unknown combination or buy a Patton E1 gateway than can do all sorts of tricks with PRI .
