Broadcast Announcements
VISM supports announcement requests for a single endpoint or connect ion. The r equest ma y onl y
specify a single announcement to be played on a single endpo int i n a si ngle dir ecti on. Br oa dcas t
announcements are not supported.
Multiple Announcement Requests for the Same Endpoint
If an announcement is being played on an endpoint (in o ne dir ect ion) and a subs eque nt a nn oun ceme nt
request is received for the same endpoint (in the same direction), the playing announcement will
continue and the new announcement request is ignored.
If an announcement is being played on an endpoint (in o ne dir ect ion) and a subs eque nt a nn oun ceme nt
request is received for the same endpoint (in the other direction), the p layin g a nno uncem e nt i s stopp ed
and the new announcement is then played. Events are not g en er ated for th e st oppe d an nou ncem en t.
Announcement File Server
Announcements are contained in an announcement file server, which resides on an IP network rea chable
from the VISM using Trivial File Transfer Protocol (TFTP).
Announcement File Server Name
You can configure the announcement file server node name on the VISM the same way that you
configure a node name for the TFTP server.
Announcement File Server Directory Structure
You may use any directory or path on the file server as the main directory for storing announcement files.
If you do not provision an announcement path prefix on VISM, the main an nouncement file directory is
the default TFTP directory on the server. If a path prefix is provisioned, this prefix is used as the main
announcement directory. If the prefix is not absolute (does not begin with a forward sla sh (/)), the prefix
is relative to the default TFTP directory.
You can configure codec subdirectories under the main announcement directory on the announcement
file server. A codec subdirectory exists for each codec used for announcement files.The subdirectories
may be one or more of the following:
•g711u/
•g711a/
•g726_32k/
•g726_24k/
•g726_16k/
•g729_a/
•g7231_high_rate/
•g7231_a_high_rate/
•g7231_low_rate/
•g7231_a_low_rate/
