I am trying to create a busy/no answer call forward to an external number. Once activating call forwarding on the PDN and PhDN both completes the process of forwarding to cell. However, if the call is not answered within a certain time frame, the call returns to the PhDN. Listed below are the actions performed for the procedure and switch information.
CTX 670 5.20 MT61.

1. Created ECF-B/NA button= External Call Forwarding Busy no Answer
2. Programmed ECF-B/NA button= #9867>press ECF-b/na >select PDN and PhDN>entered CF# (xx91xxx-xxx-xxxx)#08(ring timer)#>pressed ECF-B/NA button [Data Programmed}
3. Activated EFC by pressing button.

Other information
Extension have 1 PDN and 2 PhDN
Hunt Group exist
PhDNs have ownership of PDN
DKT setting Call Progress Dependency is set to Line Mode and tested the above with it set to terminal mode.

Is ringing the PhDN after time lapse a normal operation and if so why is not happening on the PDN?

Thanks
