Call Monitoring (ChanSpy)

Creating a dialplan

1. Go to the "Modules" - "Dialplan Applications". Create a new dialplan.

New Dialplan app

2. Enter the name "Eavesdropping". Specify the "number to call the application", here we will use the template "911XXX" - XXX means all three-digit numeric numbers. In the "Type of code" field, specify "Dialplan Asterisk"

Template of parameters for dialplan

Templates

Further functionality you can choose from three options:

1. Eavesdrop on a conversation

It becomes possible to eavesdrop on someone else's conversation, so that neither the operator nor the client will suspect anything

In the tab "Programme code" insert the following code:

1,Answer()
n,ChanSpy(${CHANNEL(channeltype)}/${EXTEN:3},qw)
n(hangup),Hangup();

The first implementation option

ChanSpy(SIP/${EXTEN:3},qw) - note that the application number will be passed as EXTEN. If you dial 911101, the internal number 101 will be dialed. The first three digits are cut off.

If you change the length of the template, then you should adjust this line.

When using PJSIP, the command will look like ChanSpy(PJSIP/${EXTEN:3},qw)

2. To intervene in the conversation

In the tab "Programme code" insert the following code:

1,Answer()
n,ChanSpy(${CHANNEL(channeltype)}/${EXTEN:3},qBx)
n(hangup),Hangup();

The second implementation option

The differences are only in the parameters for ChanSpy

3. "Whisper'' to a colleague

In the tab "Programme code" insert the following code:

1,Answer()
n,ChanSpy(${CHANNEL(channeltype)}/${EXTEN:3},wvq(4)x)
n(hangup),Hangup();

The third implementation option
