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 directly available from AlphaPro, but can be set from the event handler and must be programmed in the NVRAM memory of the AMC-IP. The parameter is:

You can program this parameter from the event handler:

Transmit busy tone (Q1) when the call is ended

Additional information

The actual parameter in the NVRAM 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 #

• 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
