NEC SL1100 cannot defeat the Recall function

[cablemanchris]

I just heard from my customer that the SL1100 unit I installed last year has never worked properly and they just haven't told me about it so I am trying to put out a rather large customer issue at this point.

Apparently if the Operator transfers a call to an extension, they want it to ring for 20 then go to the extension's voicemail. The other units I installed did this out of the box but this one is recalling back to the operator.

If I set 24-02-03 below 24-02-04 then it rings forever and never goes to VM. If I set 24-02-04 lower than 24-02-03 then it hits the recall timer and rings back to operator. If I transfer to VM directly it goes just fine.

I tried setting the extension CFWD busy/no answer to 102 but as near as I can tell it ignored it.

Can anyone give me a clue how to get this unit to ring 4 and go to extension VM? I am sure that it easy but I am blinded by rage at this point! Please help!

verify 24-09-02/02/02/02 is set to go to VM pilot number.

I switched it from CFWD->120 to CFWD->3999 and it worked like a charm! Thank you so much!
