We use several commands to control what CLOP is sent out by any given extension, be it analogue, Digital, IP or Virtual. There are 4 widely used parts to this command.

The use of this command relies on the network ‘allowing’ the PBX to predetermine what CLI is sent out on each call. Generally this is a feature you have to have enabled with the circuit provider and they will only let you send out numbers proven to belong to your company.

The attachment of a CLI to an extension is formed of two parts – the first part of the string and the second part of the string.

The first part is held within a table of up to 15 different variations (CM>1325/5005).

The second part is attached directly to the extension using CM>1212.

CM>1325 – Permits or Denies the sending of CLI to the network CM>5005 – Builds a table of up to 15 different National area codes CM> 1212 – Attaches the last 4 digits of the CLI to an extension CM>1213 – Attaches the rest of the digits as determined in CM>5005 to the extension.

Below we break down examples of each command:

CM> 1325: 1001 = 1

This means that extension 1001 is permitted to send out a CLI to the network as it’s own “CLOP”. If the Second Data had been a Zero then the extension will be denied sending a CLOP (circuit vendor permitting).

CM> 5005: 01 = 0190833

This means that we have within table number 01, the first part of a number which is 0190833. You can have different types of number in table number 00-14. The last four digits are assigned directly to the extensions in the final command...

The following two commands are made up of the Command, followed by the Extension, followed by the type of number to be sent:

CM> 1212: 1001 = 1001

This means that extension 1001 is going to attach the digits “1001” to the CLI string it sends out to the network when making an outside call.

CM> 1213: 1001 = 01

This means that extension 1001 will use whatever number has been configured within table 01, using CM>5005 as the first part of the string.
