ELIMITERS
Second number delimiters are available in PRI Gateways only.
Note
To dial an outgoing 2B call, you dial the service prefix for 1B calls and the two
B channel phone numbers. Because some H.323 endpoints do not support
dialing long number strings or two phone numbers, you can use a delimiter to
indicate to the Gateway the end of one number and the beginning of the other.

Configuring Outgoing Call Delimiters
Dialing Example 4: 2B video calls
The number string 821816455318* is a 2B video call from an IP network
terminal to an H.323 endpoint on another IP network or to a terminal on the
ISDN network. Both B channels have the same number. This number string
consists of:
82—The service prefix for a 2B video call.
1816455318—The destination phone number including the area
code.
*—The second number delimiter. The second number delimiter tells
the Gateway to dial the destination phone number a second time.
Dialing Example 5: 2B video calls
The number string 821816455318*1816455319 is a 2B video call from an IP
network terminal to an H.323 endpoint on another IP network or to a terminal on
the ISDN network. The B channels have different numbers (or your endpoint
does not have two phone number fields). This number string consists of:
82—The service prefix for a 2B video call.
1816455318—The destination phone number including the area
code.
*—The second number delimiter.
1816455319—The second B channel number including the area
code.
Dialing Example 6: 6B bonded high quality video calls
The number string 867455001 is a 6B bonded high quality video call from an IP
network terminal to an ISDN network terminal. This number string consists of:
86—The service prefix for 6B bonded calls.
7455001—The phone number of the destination terminal.
