Viking K-1900-6-IP Product Manual page 14

19. In-Band Audio Call Progress
The In-Band Audio Call Progress Detection can be set to Enabled or Disabled. In-Band Audio Call Progress detection
should be enabled in applications where you are making an outbound call through your VoIP phone system and are
relying on In-Band analog audio for ringback or busy detection. The factory default is: Enabled.
20. In-Band Audio Detection Sensitivity
The In-Band Audio Detection level (Sensitivity) can be set from 1 to 9 (1 = minimum setting, 9 = the highest sensitivity,
factory set to 5). Increasing or decreasing the sensitivity may be required in applications where you are making an
outbound call through your VoIP phone system and are relying on In-Band analog audio detection. The K-1900-6/7-IP
must be momentarily powered down after changing the In-Band audio detection level, in order for the new setting to
take effect.
21. Call Length Time Out
This feature selects the maximum length of time that calls can be connected. Programmable in increments of 1 minute
up to a maximum of 9 minutes or disabled. With the call length disabled, the K-1900-6/7-IP phone must rely on a call
ended signal, busy signal, silence or touch tone # to hang-up.
Note: The factory default is 3 minutes.
22. Dial Next Number on Ring No Answer
If enabled and a ring-no-answer is detected, the K-1900-6/7-IP phone will dial the other phone numbers.
Note: Factory set to redial if not answered after 7 rings.
23. Dial Next Number on Busy
If enabled and a busy is detected, the K-1900-6/7-IP phone will dial the other phone numbers. Notes: This feature is
enabled in the factory default setting. If the busy signal is interrupted with a promotional message, contact your central
office to have it removed. In-Band Audio Call Progress must be enabled (factory setting) if your system provides analog
busy signal.
24. Off Hook Dialing Delay
The Off Hook Dialing Delay can be set to 1-6 seconds or "No Delay" (factory set to 1 second). This is the amount of
time after going off hook before the first number is dialed.
25. Handset Default Volume
The Handset Volume can be set to begin at any level (1-4) on a new off hook. This can be fixed at any level, or set to
restore the last volume setting on each call. When set to a fixed level, the volume button on the handset will not have
any effect. The factory default setting is 1.
