Note VISM supports G.729ab for connections and endpoints. If an announcement is to be played on a
connection or endpoint provisioned for G.729ab, it must be recorded in G.729a.
For example, if the announcement server all-lines-busy.au file is encoded in both g711a and g729a, the
following pathnames and files exist on the file server (assuming the default TFTP directory is tftpboot):
•/tftpboot/g711_a/all-lines-busy.au
•/tftpboot/g729_a/all-lines-busy.au
When the call agent requests that the announcement server all-lines-busy.au file be played toward one
end of an established call, the VISM determines the codec being used for that call and plays the
corresponding announcement file.
When the call agent requests that an announcement be played toward the TDM network on an
unconnected endpoint, the codec used is specified by the VISM announcement preferred codec, configured
with the cnfannprefcodec command.
You can configure another level of directories to group announcement files by language. Specify these
directories by the call agent (or when provisioning the VISM) as part of the announcemen t file name.
For example, the call agent might specify the english/ann1.au announcement file name. If the file is
encoded in G.729a and the prefix is /tftpboot, the file is located at /tftpboot/g729_a/english/ann1.au.
Examples The following example shows that the /cisco/vism_ann path is designated as the prefix directory path
from which to retrieve announcement files from the announcement file server:
cnfannpathprefix /cisco/vism_ann
