INTERNAL CALLS

In some cases a user may want to make phone calls between the handsets registered to the same DP715 Base Station when it is used as a standalone unit, without the use of a SIP server. This feature will also be applicable when the DP715 Base Station is used with Hunting Groups and is registered to SIP server only with one master number. In such cases users still will be able to make internal calls by following these steps:

1.Press INT.

2.Internal appears in the display.

3.Select the number of the handset (keys 1-5) you wish to call.

4.When you have completed your call, press to hang up.

Note:Both Handsets should be registered to the same DP715 Base station.
