We're using active calls subscription to monitor all the calls in many different extensions and we can see a lot of activity.

Now we need to link a transferred call for example :

The customer calls our Main extension

The receptionist answers and then transfers it to extension #3

We can see the call on extension #3 with one sessionId and also we can see the call for the main extension showing on active calls method, however, we don't see how we could link them.

Their sessionId is different.

Any help?
