4. Disconnect Tone Configuration
This application note is going to describe the procedures of configuring the
disconnect tone on WellGate FXO GateWay in order to release LINE ports of
WellGate FXO GateWay after PSTN/PBX caller party is hung up.
4.1 What is Disconnect Tone
A caller make a telephone call to Gateway from PSTN side, WellGate FXO
GateWay will answer the call automatically. If the IP side of other VoIP devices do
not answer the call and the caller hang up the call, the PSTN/PBX will give
Gateway a disconnect tone automatically. Or, both devices are installed with
WellGate FXO GateWay and connect to local PSTN. If both parties are in talk
mode, one side hang up the call the WellGate has to recognize the disconnect
tone from local PSTN. The WellGate FXO GateWay gateway will recognize this
disconnect tone and release the LINE port with the pre-defined busy tone or
reorder tone from WellGate FXO GateWay tone table.
If the other VoIP device of IP side hangs up the phone, the gateway will release
the LINE port automatically without analyzing disconnect tone from PSTN/PBX.
There are three parameters received from PSTN/PBX.
-
High level frequency and Low level frequency
-
Tone Cadence (ON/OFF intervals)
-
Tone level
These parameters have to be properly configured to WellGate FXO GateWay in
order to recognize disconnect tone correctly. Each different PSTN/PBX have
different parameters. So, WellGate FXO GateWay has to configure tone table
when LINE port connect to different PSTN/PBX.
