CPL reference
The VCS does not currently support some elements that are
described in the CPL RFC. If an attempt is made to upload a
script containing any of the following elements an error message
will be generated and the VCS will continue to use its existing
policy.
The following elements are not currently supported:
•
time-switch
•
string-switch
•
language-switch
•
priority-switch
•
redirect
•
•
log
•
subaction
•
lookup
•
remove-location
On executing a
proxy
node the VCS attempts to forward the call
to the locations specified in the current location set. If multiple
entries are in the location set then this results in a forked call.
If the current location set is empty the call is forwarded to its
original destination.
The proxy node supports the following optional parameters:
timeout=<1..86400>
Timeout duration, specified in
seconds
stop-on-busy =
"yes" | "no"
Whether to stop searching if a busy
response is received
The proxy action can lead to the results shown in the table
below.
failure
The proxy failed to route the call
busy
Destination is found but busy
noanswer
Destination is found but does not answer
redirection
VCS is asked to redirect the call
default
CPL to run if the other results do not apply
The CPL can perform further actions based on these results.
Any results nodes must be contained within the
proxy
node. For
example:
<proxy timeout="10">
<busy>
<!--If busy route to recording service-->
<location clear="yes" url="recorder">
<proxy/>
</location>
</busy>
</proxy>
proxy
reject
If a
reject
node is executed the VCS stops any further script
processing and rejects the current call.
The custom reject strings
status=string
and
reason=string
options are supported here and should be
used together to ensure consistency of the strings.
