4 Enter the following command to switch to the directory containing the
add_language and change_codec: utilities:
cd /usr/app/app.dir
5 Enter the following command to run the add_language utility:
./add_language
6 Enter the appropriate response to the prompt to add UK English language
prompts.
7 Enter the following command to run the change_codec utility:
./change_codec g729a
8 Stop and restart IP Messaging by entering the following commands:
cd /opt/3com/VCX/UMS/vcx-scripts/init.d
./S60ums stop
./S60ums start
9 Log in to the secondary IP Messaging server and repeat steps 2 through
8.
Note that steps 5 and 6 may be optional. If, in the example, you were
changing to the G.729a codec with US English language prompts, steps 5
and 6 would be unnecessary because the US English prompts are already
enabled.
Converting Prompts
and Messages to a
Different Codec
IP Messaging supports only one codec at a time and operates with the
G.711a codec by default.
If you want to switch to a different codec (for example, switch from the
default codec to the G729a codec), you can run the change_codec utility.
However, if you run the change_codec utility on an IP Messaging system
on which custom prompts have been recorded and voice mail messages
have been saved in the previous codec format, those prompts and
messages will be lost. To preserve existing custom prompts and voice mail
messages, run the codec_data_convert utility before running the
change_codec utility.
When you convert custom prompts and voice mail messages to a
different codec, you should run the codec_data_convert utility on both
the primary IP Messaging server and the secondary IP Messaging server.
The following example assumes the IP Messaging system is operating
with the default codec (G.711u) and the default set of language prompts
