I have a Strata DK424 system that goes into a Repartee voice mail system. In order to transfer to voice mail the phones are usually programmed CF-BN ###-301, Call Forward Busy/No Answer to ext 301 (voice mail. On one phone that I'm having problems with, I can't program either Call Forward to No Answer or Call Forward to Busy/No Answer. I can program Call Fwd All to voice mail. On some of the phones, one in particular, it just rings once then opens up the microphone.

I'm wondering if it's related to the answering or ring setup on this one since when you call it, it only rings once thenopens up the microphone. The phone is a 10 button DKT-2010-SD I believe.
