The general configuration of the DECT system, as well as the allocation of the DECT system name and password are performed in this submenu.

  • System Name: The name of the DECT system. This name determines the name of the LDAP object in which the system parameters are stored. For a replication from an innovaphone PBX, a corresponding DECT Object must be created in the PBX.
  • Password: The password for the encryption of all passwords in the LDAP database. If the user data from an innovaphone PBX is replicated, the PBX password must be configured.
  • Subscriptions: The type of handset registrations (subscriptions).
    • With Activation: Subscriptions are allowed for known handsets with their IPEIs and after activation of single handsets. IPEIs can be configured in the anonymous page or in the user input screen with specification of an authentication code (AC). For anonymous handsets the system AC must be set and used. The subscription time of two minutes can be started with the IPEI link of the anonymous or user list.
    • Allowed: Subscriptions of all handsets are allowed without activation, also for unknown handsets.
    • Disabled: Subscriptions are not possible.
  • Authentication Code: The authentication code that must be specified when subscribing handsets without an user assignment (anonymous).
  • Tones: Various tone schemas can be used here.
  • Default Language: The default language which is used if no language is selected in the handset. If the handset does not send language information to the system, this setting determine which language that is displayed for some text messages (for example hung-up and disconnected).
  • Enabled Carriers: The RF-carriers enabled for use in this DECT system.
  • Local R Key Handling: The features of the R key are implemented in DECT systems on relevant VoIP protocols and should always be enabled in the innovaphone PBX.
  • No Transfer on Hangup: A call is being made on a telephone. A second call is received on this telephone (call waiting); the first call is put on hold and the second call is answered. If the second call is ended by replacing the handset, then the first call on hold is signalled specially on this telephone.
    If this check box is checked, then a call on hold is ended.
  • No On-Hold Display: Interop option to avoid Issues with Kirk Endpoints (Not relevant for IP6X DECT Phones).
  • Display Original Called: If this is ticked, the original called instead of the diverted party is shown if the call is diverted.
  • Coder: The coder is the type of voice data compression. This coder is used for all external calls. If the remote VoIP device does not support the configured encoding, an encoding supported by both parties is negotiated.
  • Framesize: The packet size/interval of the voice data in ms. Bigger framesize will enlarge delay. Smaller framesize increases network and processing load. Find a compromise that fits your needs and resources.
  • Exclusive: A checked check box enables the selected coder as exclusive. In this way, use of the configured encoding (coder) is forced. This can result in call failure in the event that this device and the remote VoIP device do not support a common coder.
  • Silence Compression: A checked check box enables Silence Compression (SC). In other words, no voice data is transmitted during pauses in the conversation.
  • Secure RTP Key Exchange: The key exchange method is to be configured here. See the phone configuration for more details.
  • Secure RTP Cipher: It enables encrypted media streams (SRTP). For perfect privacy you must use encrypted signaling protocol (e.g. SIPS) to hide exchange of SRTP keys.
  • Disable Wideband Audio: Disable use of G722.2 (AMR-Wideband).
