Hi Leslie,<br>
<br>
The next messages after setup are the ones that determine how the user
hears ringback. If the PSTN sends Proceeding, Alerting, or Facility
with a Progress Indicator IE and that Progress Indicator ends in 8 then
the IOS gateway and CM must cut through audio immediately. This allows
the user to hear any inband tones provided by the transit PSTN gear or
by the far end customer premise equipment.<br>
<br>
I am not aware of a single one-size-fits-all solution to this. Some
services, such as American Express, send PI=8 to play prompts to caller
at the beginning of the call. In this case it is necessary to cut
through the audio. You may call other CPE equipment that provide PI=8
but then fail to provide inband audio of either announcement or
ringback.<br>
<br>
That said there are a few tools at your disposal:<br>
