Why Is the Busy Tone Played After I Dial a Phone Number?

Why Is the Busy Tone Played After I Dial a Phone Number?

  • (Versions later than V200R002C00) The possible reasons are:

    • The local call prefix is not correctly configured.

      When you call a local phone number, the busy tone indicates the local call prefix is not configured or incompletely configured. Ensure that the following mandatory parameters of the call prefix are configured correctly: call-type, digit-length, and prefix.

    • The called party's number does not exist.

      You can run the display voice pbxuser or display current-configuration command to check the existence of the called user or configuration integrity. For a POTS user, mandatory pbxuser parameters port and telno must be set correctly. For a SIPUE user, mandatory pbxuser parameters sipue and telno must be set correctly.

    • The called party has configured the call restriction services.

      Run the display voice pbxuser or display current-configuration command to verify that the called party has configured the call restriction services such as call rejection and selective call acceptance.

      If the fault persists, contact Huawei technical support personnel.
