<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">I know a while back (we’re
talking a few years here) calls to certain toll-free IVR based systems were not
working in a similar fashion. The reason for this was that the IVR although it
had answered the call was not sending a certain message to the phone company
until the caller had gone at least one step into the IVR. By not sending this
one particular Q931 message they were not billed for that first few moments of
a call. The side effect of not having sent that message meant CUCM also
thought the call was not terminated and therefore was not changing the phone
status from “Ring-out” to “connected”.</span></p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">It is likely the collect call
might operate in a similar fashion. Have someone test an inbound collect call
and check the status on their phone when they’ve answered. Is it showing “connected”
or something else?</span></p>
