Patent Images
1. An apparatus for transferring a call from a first port of an applications processor for a telephone switch having an internal alternate line to a second port of the applications processor, comprising:
- means for seizing the second port;
means for detecting dialtone at the second port;
means for confirming the detection of dialtone to the first port;
means for initiating a transfer of the call to the alternate line; and
means for transferring the call to the second port, wherein said alternate line is configured such that said alternate line will not go off-hook prior to said call being connected to said second port.

Abstract
The reliability of call transfer in a PBX can be improved by verifying the availability of a destination port before a transfer is attempted. The incoming call is routed to an alternate line after the interrogation occurs. Once the availability of the desired facility is confirmed, the call can be picked up by the destination port.
