Some Dial Plan Examples ( II )
Dial Extension (IVR) Examples
Interactive Video Response (IVR), also called
extension dial-in, is an automated answering
system that directs the call to the IP endpoint
indicated by the caller. The caller uses
telephone tones (DTMF) to enter the H.323/
SIP alias or extension.
IVR is useful in case a limited amount of
numbers, e.g. ISDN PRI or BRI lines, is
available.
An example shall be provided:
1.
An endpoint user calls a Dial Extension
service number.
The Entrypoint activates the
Welcome
2.
picture and sound.
3.
The Entrypoint, when set in the dial plan,
shows the DTMF Information screen.
4.
The endpoint user enters the extension
(H.324m/H.323/SIP alias) followed by the
# (pound-sign) to indicate end of number.
5.
The Entrypoint starts to call the endpoint
and the
Connecting
picture and sound are
activated.
6.
When the call is connected audio and video
are transmitted through the Entrypoint (SIP
to SIP calls and H323 to H323 calls will
only go through the Entrypoint when
Allow
Forwarding
is set to No).
It is not possible to configure ISDN BRI
lines for special functions like dial out
only. The Entrypoint will automatically
select a free BRI line for H.323 to 3G
calls and possibly block a DID or an
IVR menu when the BRI lines have
different numbers.
Consequently, we strongly recommend
that all ISDN BRI lines have the same
number range.
