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.
This is how it works:
- 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: Figure 1. Voice path between caller and third party during a trombone operation
Note: Because the trombone operation uses the
TDM bus, this function requires a DTTA card installed in the Blueworx Voice Response system.
