Description

Party A calls party B (which is the demonstration program) and requests a transfer to party C. nccxfer (party B) then calls party C. It reports success or failure at one of several stages, depending on the selected transfer method. (If -m 4 is specified on the command line, nccxfer asks party C whether it should complete the transfer, or report failure.)

Procedure

Begin with three telephone lines: two (A and C) with two 2500-type telephone sets, and one (B) connected to the AG board. Lines B and C must be connected to a common PBX.

To run nccxfer:

  1. Make sure that you specify the proper AG board and MVIP stream, and start agmon.

    

  2. Start nccxfer by entering the following at the prompt:
    

    
nccxfer [ -b n -s n:m -p protocol -i n -m n ]
    
Make sure you specify one of the transfer methods.
    

  3. From line A, call line B.
    

    
The demonstration should answer.
    

  4. When it requests an extension to try, dial the extension of line C.
    

    
The demonstration calls line C.
    

  5. Answer line C.
    




With transfer method 4, the demonstration offers you a chance to refuse the call. The other transfer modes report success or failure at earlier stages, sometimes before the transfer is actually completed.
