# Call Monitoring (ChanSpy)

## Creating a dialplan

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

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**"

## 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:

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

{% hint style="info" %}
**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)**
{% endhint %}

### 2. To intervene in the conversation

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

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

<figure><img src="/files/odlpciyARnWWu7IUgAhI" alt=""><figcaption><p>The second implementation option</p></figcaption></figure>

{% hint style="info" %}
The differences are only in the parameters for **ChanSpy**
{% endhint %}

### 3. "Whisper'' to a colleague

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

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

<figure><img src="/files/iTrrxd8tr9A0Nuywnl57" alt=""><figcaption><p>The third implementation option</p></figcaption></figure>

{% hint style="info" %}
The differences are only in the parameters for **ChanSpy**
{% endhint %}
