•Subscriber is a VoIP end device
Jitter buffer
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.
Echo cancellation
The system compensates for local echoes and reverberation effects during internal VoIP calls.
SIP alert info
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.
External and internal calls
Device uses this selection of call types to signal call tones.
External, internal, group, door and alarm calls
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.
Allowing Update Messages
If the function is enabled and Online name search is activated, the name will be updated while the connection is being set up.
When Blind Transfer is activated and the function is enabled, the name as well as the telephone number will be updated while the connection is being set up.
Note: In the event of problems while the connection is being set up, this function should be disabled as a possible cause.RTP encryption
Allows an exception from the default settings of the PBX for the corresponding VoIP subscriber. The default setting is Adopt from Administration ->SIPS/SRTP internal (default).
Applying the exception is required if:
•The corresponding phone does not support the settings of the PBX. This may cause problems e.g., during a call being established.
•You must circumvent the settings of the PBX for test purposes or trouble shooting.
Note: The settings of the PBX for the corresponding subscriber and the settings of the phone must match.Adopt from Administration ->SIPS/SRTP internal (default)
The PBX setting applies for the subscriber.
Only encrypted
Example: SRTP is not enabled in the PBX. The phone requires an enabled SRTP.
Only unencrypted
Example: SRTP is enabled in the PBX. The phone does not support SRTP.
Format of transferred telephone number
The PBX supports several formats to display the country code of incoming calls on the display of the VoIP phone being called, e. g. adjusted to a small display.

•Reading with a bar code scanner enabled and connected to the computer (e. g. via a USB interface)
•Reading e. g. on the menu oft the phone or on a label
Note: If a MAC address has been entered and assigned to a subscriber, the corresponding phone can already be provided with provisioning data during its first boot process.IPUI (only COMfortel WS-500X Handsets)
