This USED to happen only if I was on a call, and someone already on call wating, then when a third call come in, they get a FAX response (rather then a busy signal).
However, over the last several weeks, this has gotten a lot worse.
Here is the sequence:
1) I hear 1 ring, short -- and there is no caller ID display [so this call was redirected before the caller ID was sent]
2) This can repeat one more time
3) usually, on the third call, they get thru. Telling me a FAX sound was all they got before.
NO -- I do NOT have any FAX machines connected, hardware or software.
YES, I checked all of the phones etc, nothing should or could have responded -
lest it be a FAX service.
What can I do????????
