Force analog phone to go on-hook by tone

When using analog telephones without handset (e.g. phones with a single push button) on ATLB/ATLB-12 boards, and the conversation is ended by the intercom station, a signal must be sent from the AlphaCom to the phone to make it go on-hook.

Many single push button phones have an option to go on-hook when they receive a DTMF signal or a busy signal.

It is possible to configure the AlphaCom to send a tone after the conversation is ended.

The setting is not available in AlphaPro, and must be programmed in the NVRAM memory of the AMC-IP. The parameter is:

ex_profile.glob_const.hs_tone_call_res = x
.
0 = default behavior
1 = Busy tone
10-19 = DTMF tones 0-9
20 = DTMF tone *
21 = DTMF tone #

You can program this parameter from the event handler:

Transmit busy tone (Q1) when the call is ended

• This feature is only valid for ATLB stations, other stations using handset will get standard off-hook tone when the conversation is ended.
• Software requirement: AMC software 10.60.3.2 or newer
