Dialogic 6.2 manual Transferring Calls, November 176

5 - Transferring Calls

This chapter describes transferring calls using the Bfv API-level and BSMI-level call control functionality.

Note: The Dialogic® Brooktrout® SR140 Fax Software does not support this functionality.

Call transfer is a method of redirecting an incoming call to an internal line or “transferring” it from one channel to another channel. The phone network can also manage and disconnect the call. Call transfer functionality is supported on the board and inside a public switch. Depending on the protocol in your network, transfers use either the same channel for transfers, such as an analog line, or use two B-channels for transfers, such as explicit call transfer in Europe.
