Which key types can I use with the SIP virtual port?

If the SIP bound virtual port is to be used in 4 wire, IFB or as a conference member then all of the standard key types are available to be used. If the SIP virtual port is to be controlled by a panel phone key the following three dial keys types are available.

Each phone key type behaves in a similar manner to establish the call, when the key is pressed down selects the dial pad and menu list of pre-stored numbers, including the last dialled number to help automate the dialling process. The incoming call can be set to ring the panel. Once the call is established, the SIP phone key can be put on hold and then any panel can speak to this call as if it is a standard 4 wire.

The SIP phone key can be set to auto dial a pre-set number entered in the Gateway Editor. So pressing the key down auto dials and connects to the remote SIP alias. SIP dialling is reasonably quick (typically a few 100mS depending on the network)

The SIP key can also be set to auto answer, so an incoming call is automatically answered (no ringing) and the callers’ voice is heard without the need to interact with the key. These last two features can be used together to offer an “intercom-like” user experience when connecting to third-party systems.
