Some Dial Plan Examples (
II
)
Dial Extension (IVR) Dial Plan 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:
An endpoint user calls a Dial Extension 1.
service number.
The 3G Gateway activates the 2.
Welcome
picture and sound.
The 3G Gateway, when set in the dial plan, 3.
shows the DTMF Information screen.
The endpoint user enters the extension 4.
(H.324m/H.323/SIP alias) followed by the
# (pound-sign) to indicate end of number.
The 3G Gateway starts to call the endpoint 5.
and the
Connecting picture and sound are
activated.
When the call is connected audio and video 6.
are transmitted through the 3G Gateway
(SIP to SIP calls and H323 to H323 calls
will only go through the 3G Gateway when
Allow Forwarding is set to No).
Dial Extension (IVR) Examples
Example 6: 3G to SIP IVR
Entry details: Enabled: Check
Name: 3G-SIP-IVR
Net type: H.324m
Prefix: 1234790
Suffix: Service type: Dial Extension
Arguments: Net Type: SIP
A V Mode: Auto
Prefix:
Suffix: @<SIP_Proxy_Address or Registrar_Address>
Allow Forwarding: No
When dialing number 1234790 on a 3G handset, one is connected to
<UserInputNumber>@<SIP_Proxy_Address or Registrar_Address>, where
UserInputNumber is the number keyed in by the user from within the IVR
menu.
Example 5: 3G to H.323 via a Phone book
Entry details: Enabled: Check
Name: 3G-H.323- Phonebook
Net Type: H.324m
Prefix: 123489
Suffix: Service Type: TMS Corporate Directory
Arguments: Net Type: e.g. H.323
A V Mode: Auto
Prefix:
Suffix: Allow Forwarding: No
When dialing number 123489 on a 3G handset, one is connected to
an TMS Corporate Directory, from which an H.323 or SIP endpoint can
be selected. Note that the
Net Type to be selected in arguments is
irrelevant, since the endpoint to be called is selected from a phone
book.
It is not possible to configure ISDN BRI
lines for special functions like dial out
only. The 3G Gateway 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.
