Proceed as follows:
1.Configure a VoIP channel as an internal VoIP channel for each planned internal VoIP subscriber.
2.If necessary, configure the SIP port of the internal VoIP registrar.
3.Create internal numbers for the VoIP subscribers.

5.Configure the VoIP end devices. To do this, you need the following information:

*Note: You will find notes about how to configure different VoIP end devices on the Internet (see Auerswald Service Portal).
6.Check whether the VoIP subscriber was successfully registered on the PBX (Monitoring > Status int. VoIP subscribers).
7.If necessary, enable DiffServ, to increase VoIP call quality (Quality of Service (QoS)).
8.If necessary, make the VoIP settings (Jitter buffer, Echo cancellation) for the VoIP subscribers to improve the call quality.
