General settings

The general settings allow the basic configuration of a phone.

  • In the number text box, the extension of the telephone is specified.
  • The caller ID is the name or number that dialog partners see on their phone displays.
  • Default provider determines one provider this phone uses for external calls. Please note that this overwrites your outgoing dial patterns.
  • Language sets the spoken language of the audio prompts. This setting defines which prompts are used internally. The language setting on a provider account determines the language being heard when external calls come in and overrides this settings.
  • Ring length is the period in seconds before hanging up or going to voicemail. Indefinitely disables any interference by AskoziaPBX. In case notifications are not configured (see Notifications in the Services menu) but a ring length has been defined, AskoziaPBX refuses the call by signaling "unavailable" after the end of the time.
  • The hardware port is the physical hardware port the telephone is connected to. The telephony ports section of the Connectivity menu provides more information.
  • A description for the phone can be added. The description is ignored by AskoziaPBX but may be handy to clarify a phone's purpose, user or location.
General settings


  • For public access, check allow this number to be reached over the Internet. You can use a friendlier alias instead of the extension number. A possible form could be myName@myIP.
  • Block providers allows to prevent access to the selected provider. This may be useful if a telephone should not have access to a certain provider to save costs. If all providers are blocked, the telephone can only be used internally.

Manual attributes

Manual attributes are only required in a few special cases and should generally be used with caution and only by experienced administrators.

As manual attributes are only valid in specific contexts, manual attributes for an analog phone are only valid in the context of this particular phone.
