I have my answering machine setup to pickup the phone after 4 rings (20 seconds) for many years without any problem for OBi 200. Recently, there is problem:
I, standing next the answering machine, do hear the answering machine making announcement after 4 rings, but the call is not picked by my answering machine. The caller will hear the 5th ring and go directly to the Google Voicemail.
Strangely, if I setup the answering machine to pickup call after 2 rings (10 seconds), the answering machine will pick up the call as it used to.
I am very certain this Obi 200, not my answering machine, is the problem because I've tried the same answering machine on another OBi200 without any issue.
The firmware of my problematic OBi 200 is 3.2.2 (Build: 5859EX). The firmware of my other good OBi is 3.2.1 (Build: 5757EX). I did try to downgrade the firmware manually, but got "Checksum error".
By the way, I also have Anveo E911 setup on SP2 of the problematic OBi200.
