•
The gateway starts the call to the IP endpoint and the "Call proceeding" picture and sound are initiated to
your endpoint.
•
When the call is connected audio and video are transmitted through the gateway.
IVR
Interactive Voice Response (IVR), also called extension dial-in, provides you with a single dial-in number. The
caller uses telephone tones (DTMF) to enter the extension address of the endpoint to be called. It is an automated
answering system that directs the call to the endpoint indicated by the caller.
IVR is useful if you have limited PRI numbers on your PRI line.
�x�mp�e:
•
A videoconferencing system calls into the Extension Dial-In number of an IVR service.
•
The gateway activates the 'Welcome' picture and sound.
•
The user of a videoconferencing system enters the extension (H.323 Alias) followed by the # (pound-sign).
•
The gateway starts to call the IP endpoint and the "Call proceeding" picture and sound are activated.
•
When the call is connected audio and video are transmitted through the gateway.
IVR + TCS-
This call type is the same as described above but extended by an additional method ("TCS-4") to signal the extension
address to the Gateway. In this mode the extension number can be indicated with IVR (see above) or TCS-4
signaling.
TCS-4 allows an H.320 based videoconferencing endpoint (ISDN, V.35, V.35RS366 and G.703) to dial an IP endpoint
directly, without having to (manually) enter the extension number by DTMF: The endpoint will send the extension
number as a TCS-4 signal to the Gateway. If no TCS-4 extension is sent from the endpoint, then IVR will be used.
To use TCS-4, it needs to be supported by the videoconferencing endpoint. Refer to the User Manual of the
videoconferencing endpoint to see how TCS-4 is supported.
Example:
•
A videoconferencing endpoint calls into the Extension Dial-In number of an IVR + TCS-4 service, using
<Dial-In number of this service>*<extension number>.
•
The gateway starts to call the IP endpoint and the "Call proceeding" picture and sound are activated.
•
When the call is connected audio and video are transmitted through the gateway.
•
TANDBERG endpoints allow storing the complete dial string in the phonebook to automate dial through.
Setting up Dialling Rules
Type:
Bandwidth:
Number of
significant digits:
From Nettype:
From prefix:
To Nettype:
To prefix:
DID, IVR or IVR-TCS4 (see above for details)
This value sets the maximum call rate for the given Gateway service.
Specify the number of significant digits of the incoming number that should be used to do rule
matching, and to be used to generate an outgoing number.
Please note! Setting 'No. Significant Digits' to 0 (zero) will make the GW check the whole
incoming number for rule matching.
Supported call types: H.323, ISDN, V.35, V.35RS366, G.703 (leased line), and telephone.
This setting instructs what to match on the incoming call.
NB! The significant number of digits is applied on the input, before matching From Prefixes.
The call type on the destination side.
The prefix is used to append a number to the matched number (Now without the From prefix).
The To prefix will be first in the outgoing dialed number from the gateway.
