About Dialing Out to the ISDN Network Through the Gateway
•
Dialing Example 3: 1B video calls
The number string 821816455318 is a 1B video call from an IP network terminal to an H.323 endpoint
on another IP network or to a terminal on the ISDN network. This number string consists of:
•
•
About Second Number Delimiters
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. See the
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:
•
•
•
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:
•
•
•
•
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:
•
•
Dialing Example 7: IP-ISDN-IP direct dialing—Gateway supports TCS4 (PRI and BRI Gateways only)
The number string 9825645000^3333 is a call from an IP network endpoint (Endpoint 1) to an IP
network endpoint in another zone (Endpoint 2), through a public ISDN network, as shown in
Gateway A dials using TCS4, while Gateway B is set to receive calls in TCS4 mode.

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.
82—The service prefix for a 2B video call.
