AutoCall/Offhook Alert Parameters
Auto Call / Offhook
Alert
AutoCall,
Offhook
Alert
The AutoCall option enables the local MultiVOIP to call a remote MultiVOIP without
the user having to dial a Phone Directory Database number. As soon as you access the
local MultiVOIP voice/fax channel, the MultiVOIP immediately connects to the remote
MultiVOIP identified in the Phone Number box of this option.
If the “Pass Through Enable” field is checked in the Interface Parameters window,
AutoCall must be used.
The Offhook Alert option applies only to FXS channels.
The Offhook Alert option works like this: if a phone goes off hook and yet no number
is dialed within a specific period of time (as set in the Offhook Alert Timer field), then
that phone automatically dials the Alert phone number for the VOIP channel. (The
Alert phone number must be set in the Voice/Fax Parameters | Phone Number field;
if the VOIP system is working without a gatekeeper unit, there must also be a matching
phone number entry in the Outbound Phonebook.). One use of this feature would be
for emergency use where a user goes off hook but does not dial, possibly indicating a
crisis situation. The Offhook Alert feature uses the Intercept Tone, as listed in the
Regional Parameters window. This tone is outputted on the phone that was taken off
hook but that did not dial. The other end of the connection hears audio from the
“crisis” end, as during a normal phone call.
Both functions apply on a channel-by-channel basis. It would not be appropriate for
either of these functions to be applied to a channel that serves in a pool of available
channels for general phone traffic. Either function requires an entry in the Outgoing
phonebook of the local MultiVOIP and a matched setting in the Inbound Phonebook of
the remote VOIP.
Generate Local Dial
Tone
Y/N
Used for AutoCall only. If selected, dial tone is generated locally while the call is being
established between gateways. The capability to generate dial tone locally would be
particularly useful when there is a lengthy network delay.
Offhook Alert Timer
0 – 3000
seconds
The length of time that must elapse before the off hook alert is triggered and a call is
automatically made to the phone number listed in the Phone Number field.
Phone Number
--
Phone number used for Auto Call function or Offhook Alert Timer function. This phone
number must correspond to an entry in the Outbound Phonebook of the local
MultiVOIP and in the Inbound Phonebook of the remote MultiVOIP (unless a
gatekeeper unit is used in the VOIP system).
