Net Conference
Net Conference is generally the same as the Conference feature, with the additional
specification that a Networked Station can be assigned as a conference member.
A call to a Station on one node is able to conference in a party on any other networked node. Up
to 3 Stations of the network can be members of a conference.
Operation
To conduct a conference from a Station:
1. Press the [CONF] button, during a network conversation. The connected call is put on
hold and the ICM dial tone sounds.
2. Make a Net Call to a Station on another Networking System.
3. Press the [CONF] button when the second Called Station is answered; the call is put on
hold and an ICM dial tone sounds.
4. Press the [CONF] button again; the conference voice path to all members is connected.
To cancel a Conference:
Any Station on a net conference call can hang up during the conference. The net
conference will be ended and the network path will be cleared.
Conditions
