Description
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.
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.
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 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).
