6. H323 Configuration Commands
The ITG employs ITU-T H.323 protocol for call signaling and call control. The gatekeeper
is an H.323 entity on the network that provides admission control and address translation
services. The ITG allows calls to remote gateways be routed through a H.323 gatekeeper
or not. This chapter describes commands for configuring the H.323 protocol.
This chapter is organized as follows:
l General H.323 configuration commands
l H.323 gatekeeper related configuration commands
General H.323 Configuration Commands
The following sections describe the general H.323 configuration commands.
set h323 alt_dtmf
There are two ways VoIP gateway handles DTMF relay, per H.323 and IMTC specifications.
While the “set h323 default_dtmf” command (Page 36) specifies the DTMF relay technique
the ITG employs for conveying DTMF digits to remote VoIP devices over Internet. There is still
a need for conveying DTMF digits using the alternate DTMF relay technique to certain remote
VoIP devices. This command allows users to maintain a table of IP address of remote
gateways to which the ITG will convey the DTMF tones using the DTMF relay technique other
than the one defined by CLI command “set h323 default_dtmf”.
set h323 alt_dtmf {add | del} ip_addr
Syntax Description
add
Add an entry to the table of IP address of remote gateways to which
the ITG convey DTMF tone using the alternate DTMF relay
technique.
del Delete an entry from the table.
ip_addr IP address of the remote gateway.

set h323 default_dtmf
set h323 call_name
One of the UUIEs in the H.323 Setup message that the ITG sends to a remote gateway when
initiating a call is sourceAddress. The sourceAddress UUIE is a list of alias addresses, by which
the remote gateway identifies the ITG. This command is used to set a string that the ITG will
place in the 3
rd
alias address filed of the sourceAddress UUIE in the H.323 Setup message.
set h323 call_name “call_name”
Syntax Description
call_name Call name, up to 30 characters, to be encapsulated in the 3
rd
alias
address field of sourceAddress UUIE of the H.323 Setup message.
Factory default
