TANDBERG Gateway
25
Features
Dial out to 2x64k ISDN (H.221)
For improved interoperability with legacy equipment, the two number 2x64k dial-out method can be selected from
the calling IP endpoint instead of using the standard BONDING method.
To instruct the Gateway to use this method, the calling IP endpoint has to combine the dialed number from:
• A Service Prefix offering at least 128k callrate,
• The (first) ISDN number to dial out to,
• Two stars (“**”),
• The second ISDN number to dial out to.
Example:
• An H.323 Service prefix for outgoing video calls is defined as “0” (default).
• The user wants to dial the first ISDN number 67121212 and the second number 67121213.
• The user dials to “067121212**67121213”.
• Audio and video are transported through the gateway when the call is connected.
NOT ALL ENDPOINTS WILL SEND OUT THE NEEDED NUMBER (INCLUDING THE ‘*’ CHARACTERS). TO MAKE OLDER TANDBERG EQUIPMENT
(CLASSIC SERIES, MXP UP TO F2) USING THIS SYNTAX, THE USER HAS TO SELECT H.323 AS THE NETWORK PROFILE TO BE USED. ALSO IF SUCH A
NUMBER
SHOULD BE STORED IN THE PHONEBOOK, THE H.323 PROFILE HAS TO BE SELECTED EXPLICITLY. SOME ENDPOINTS MIGHT HAVE A
LIMITITATION ON THE LENGTH OF THE DIAL STRING.
