A trombone operation occurs when a call coming in on
one Blueworx Voice Response channel
connects directly with an outgoing call on another Blueworx Voice Response channel.
- A call arrives at Blueworx Voice Response, and
the application decides that the user needs to be connected to a third
party using a trombone operation.
- Blueworx Voice Response makes
an outgoing call to the third party on another channel.
- When they answer, the third party is connected to the original
caller using the TDM bus internal to the Blueworx Voice Response system.
At this point, the connection looks like this:
