Note: This service is accessible from any extension other than an IP H.323 Dialog 4425 or Dialog 4422 extension. Rather selecting the “SIGN_ON” dynamic function key, simply dial the “75” prefix. This prefix may, however, have been modified by your system administrator.

DTMF End-to-End Dialling

At times, you may need to call external servers, such as a reservation centre server, when you are required to communicate interactively through the online transmission of various dialling codes.

Your extension makes this option available to you through the DTMF end-to-end dialling service. With this service, you can directly exchange dialling codes with a remote server, without your dialling being interpreted by your local facility.

This is processed through the exchange of DTMF codes, from which the service’s name is derived. You can hear the codes in the form of tones in your telephone.

To use this service when placing an external call:

Everything that is dialled thereafter is then directly transmitted to the remote server.
