Proceed as follows:

Requirement:

Specifies the size of the jitter buffer in milliseconds (duration of the audio signals). In this time period RTP packets are cached (lower values = lower number, greater values = greater number). Delays in the transmission and loss of packets can be compensated that way.

Local echoes and reverberation effects during internal VoIP calls are compensated.

Select the options for signalling call tones on end devices. For signalling, the Invite is sent to the end device to transfer the call types. Depending on the device, the call types are either fully converted into call tones, or converted in a simplified version. The following options are available here.

Device uses this selection of call types to signal call tones.

Device uses all the call types supported by the PBX to signal call tones.

This is the default setting when a subscriber is configured.

If problems occur with signalling on the end device, use one of the options listed above.

Select one of the existing MAC addresses.

MAC addresses already assigned to the subscribers.

Enter manually (only digits) or take over a MAC address after reading with a bar code scanner.

The MAC address of a device can be found as follows:

The IPUI already assigned to this subscriber.

Selection of an unassigned IPUI for this subscriber.

Assignment of this subscriber to a specific base station.

Display of the header file which is assigned to the subscriber.

Display of the provisioning file which is assigned to the subscriber.

The PBX supports different formats, so you can dial the contact’s phone number correctly using an LDAP request.
