Device Adapter supports the Hotline Intercom feature for the UNIStim and digital phones.
The Hotline Intercom feature adds an additional capability to the existing Hotline two-way feature that allows a call to be auto-answered after providing a ring tone for 0.8 seconds.
Hotline Intercom uses a bridged appearance on the X-port and the enhanced HTLI mnemonic to auto-answer inbound calls and auto-dial the hotline number that is configured for the Device Adapter endpoint. Administrators can use the HTLI mnemonic to the specify the Caller ID (CLID) for which auto-answer must be enabled.
The CLID of an inbound call is considered a match if it contains the string that you specify in the CLID filter of the HTLI mnemonic. For example, CLID 12345678 is considered a match for the filter 2345.
If you configure the CLID filter in the HTLI mnemonic, then:
For an inbound call that has a matching CLID, Device Adapter provides a ring tone for 0.8 seconds and auto-answers the call.
For an inbound call that does not have a matching CLID, Device Adapter provides a ring tone but does not auto-answer the call.
If you do not configure the CLID filter in the HTLI mnemonic, Device Adapter auto-answers all inbound calls.
If the endpoint is busy on another call, then the current call is put on hold.
A user can answer the intercom call through handsfree or headset, which requires the HFA mnemonic. A user can also answer this call by using the handset.
