Dialogic 6.2 Manuale Utente

Managing Calls Using IP Telephony

November 2009

227

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]
