Notification of Employment, Call Waiting

1. Go to the System file customization section

System file customization menu

1. Proceed to editing the "modules.conf" file

modules.conf file

1. Add the following code to the end of the file:

load => func_extstate.so

Code for modules.conf

1. Go to editing the file "extensions.conf"

extensions.conf file

1. Add the following code to the end of the file:

[internal-users-custom]
exten => _X!,1,Progress()
  same => n,ExecIf($["${EXTENSION_STATE(${EXTEN})@internal-hints}" = "INUSE" || "${EXTENSION_STATE(${EXTEN}@internal-hints)}" = "RINGINUSE"]?Playback(beep))
  same => n,ExecIf($["${EXTENSION_STATE(${EXTEN})@internal-hints}" = "INUSE" || "${EXTENSION_STATE(${EXTEN}@internal-hints)}" = "RINGINUSE"]?Set(TRANSFER_OPTIONS=${TRANSFER_OPTIONS}m))
    same => n,return

1. In the extension card, in the "Advanced Settings" - "Extra Options" field, set the value

[endpoint]
device_state_busy_at = 3

If the employee is busy, a beep file (a short beep) will be played to the caller, then music will be played instead of beeps until the employee answers the call

device_state_busy_at is the number of conversations at which the employee should be considered "busy", in this case the "Routing Settings" rules described in the employee card will start working.

If the problem solution does not work correctly, change the code in extensions.conf to:

[internal-users-custom]
exten => _X!,1,Progress()
same => n,NoOp(${EXTEN})
same => n,NoOp(${DEVICE_STATE(PJSIP/${EXTEN})})
same => n,ExecIf($["${DEVICE_STATE(PJSIP/${EXTEN})}" = "INUSE" || "${DEVICE_STATE(PJSIP/${EXTEN})}" = "RINGINUSE"]?Background(nomer&zanjat))
same => n,ExecIf($["${DEVICE_STATE(PJSIP/${EXTEN})}" = "INUSE" || "${DEVICE_STATE(PJSIP/${EXTEN})}" = "RINGINUSE"]?Set(TRANSFER_OPTIONS=${TRANSFER_OPTIONS}m(callwaiting)))
same => n,return
