Force analog phone to go on-hook by tone
From Zenitel Wiki
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 parameter can be set by the following event in the Event Handler:
A reset of the AlphaCom is required after having sent the configuration to the AlphaCom.
The action string is: $SNV Q1 W1 W2 W25
Q1 means Busy tone. You can change this parameter according to what tone is required. E.g. $SNV Q14 W1 W2 W25 will transmit DTMF tone 4.
Options are:
- 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.
