Answering calls
You can distinguish internal from external calls by different ringing rhythms on your telephone providing your terminal supports different ringing rhythms.

Knocking
- You receive a call while you are speaking. The call knocks. You hear the internal knocking tone once (internal call) or the external knocking tones several times (external call). You can answer the call and switch back and forth between the two calls (brokerage).
You can reject the external knocking call. If you reject it, the caller hears the busy tone if only your telephone is being called. If several telephones are being called (see call allocation) only the party with a call waiting will be disconnected.
