Calling number validation from TE’s?

This command is used to control the calling/connected number (CLI/COL) validation for calls from the S-interface.

Use case: For some traffic cases the received calling/connected number from S-bus terminal may not correspond to the system defined common access numbers- or MSN’s but must be allowed. E.g. an IVR system (Interactive Voice Response/Recognition system), connected to the S-interface and used for automatic attended purposes, receives an external call, puts the call on hold and builds up an inquiry call to the desired party. It’s here for the called party of more relevance to see the original external calling number before the transfer is executed.

##### Valid data

No |  | no validation of the calling number; S-bus terminal can build up a call with an up to 20 digit CLI/COL number, which is independent from the system defined internal directory numbers for that S-interface |
Yes (default) |  | the calling number must be validated; S-bus terminal can build up a call with the own common S-bus number or the own MSN number only |

Minimum required authority level from telephone: No

Accessible via BMS: Yes
