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.

2.The Entrypoint activates the Welcome 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.
