specified the call is rejected.

Table 30-1: Codec Selection in H.323

Similarly for an H.323 connection it is possible to specify the packet size of the transmitted voice
packets, and additionally announce length capability for received voice packets to the remote VoIP
device.

A

regular

call setup with H.323 requires about 10 TCP segments or more to be transmitted, because

several parameters are negotiated, for example the codec. Because a normal call setup is often too
slow, a fast connect is possible.

Procedure

To configure the used codec on an H.323 connection and enable fast connect

Mode

Gateway H.323

Command

Purpose

Step 1

node

(gw-h323)[h323]#codec

<?>

List all available codecs on the H.323 gateway

Step 2

node

(gw-h323)[h323]#codec

codec

[tx-packet-length] [rx-packet-length]

Specify the default codec, transmitted packet
size and length capability for received packets
for all calls over the H.323 gateway.

Step 3

Repeat step 2 to define all possible codecs used
on this H.323 gateway

Step 4

node

(gw-h323)[h323]#faststart

Enable fast connect for a H.323 call set-up

Step 5

node

(gw-h323)[h323]#exit

Change to interface configuration mode to select
one of the listed codecs in the H.323 gateway for
the H.323 interface

Step 6

node

(cfg)#context cs

Step 7

node

(ctx-cs)[switch]#interface h323

if-name

Step 8

node

(if-h323)[

if-name

]#codec

codec

[exclusive]

Define the preferred codec on a fast connect call
set up. It is not possible to redefine the packet
lengths. If the codec is specified as exclusive,
only this codec can be used for the connection

Example: Selecting an H.323 CODEC

The following example shows how to define a list of codecs in the H.323 gateway with 20 ms for the
length of transmitted RTP packets and 40 ms for the announced length capability for received RTP
packets. Further use of codec G.711 on the H.323 interface is specified. Moreover fast connect is
enabled for the H.323 call set up's.
