Answer Mode
There are two types of MWI for users to choose. Please
click the one according to the real application.
Notify User who Subscribed - The user needs to send out
SUBSCRIBE message first. When IPPBX detects new
voice message from some extension number or the
condition of the voice message is changed, it will transfer
"NOTIFY" message to the users within the valid time
subscribed.
Force Notify User- The user does not send out
SUBSCRIBE message automatically. The IPPBX will
deliver "NOTIFY" message to the users if there is a new
message or the user registers on IPPBX again.
There are several outside lines (SIP accounts) and two
ISDN lines (available based on the Phone Setting
configuration) and one PSTN for you to specify for such
extension. Please check the one(s) you want.
Use the drop down list to choose one of the interfaces as the
default trunk.
Type the MAC address to apply the settings of Auto
Provision.
Enable customer survey function – Check the box to
enable such function.
Specify the way to process incoming phone calls.
No answer after ..... – When the incoming phone call is
not picked up, it will be processed by keeping ringing,
leaving voice mail, forwarding to certain extension or
group, or forwarding a PSTN or mobile via SIP Trunk.
Please specify the waiting time and determine the way you
want to process.
Busy then – When this extension number is busy, the
incoming phone call will be processed by leaving voice
mail, forwarding to certain extension or group, or
forwarding to SIP Trunk. Please determine the way you
want to process.
