Managing Calls Using IP Telephony
November 2009 227
Using H.323 Address Forms
To allow applications to work for both SIP and H.323, the dialstring
field for BfvLineOriginateCall and BfvCallSetup accepts a
format of phone_number@ip_address (a current SIP format).
The phone number is an optional field as is the port in the
ip_address. The existing H.323 dialstrings remain unchanged and
are still supported as described below. This option provides a unified
way of placing a non-gatekeeper call that works for both SIP and
H.323.
Examples of supported dialstrings for H.323:
1234@208.242.99.10
1234@208.242.99.10:1720
Dialogic products accept the following H.323 Called Party Address
forms:
A transport address
An E.164 alias
A H.323 ID alias
Unless noted, the rules below also apply to an H.323 Calling Party
Address.
Transport Address
(IP Address) This Called Party Address must start with the identifier “TA:”
followed by the transport address.
A transport address consists of an IP address followed by the “:”
character followed by a port number or another H.323 address.
A port number is not required and, if it is not specified, then the
software uses the default H.323 port of 1720.
IP address followed by a port number example:
TA:198.133.219.25:1721
IPv6 addresses are also supported and need to be in hexadecimal
notation, inside brackets. For example;
[HHHH:HHHH:HHHH:HHHH:HHHH:HHHH:HHHH:HHHH]
