Disable Call Waiting

[jtozer]

Hi All - I just received and installed my new Obi100.  I have Google Voice and I have linked it to my Obi.  When on a call, I'd like to not receive the Call Waiting beep, instead I'd like the new caller to go to Google Voice's voicemail.  How do I disable Call Waiting permanently?

Physical Interfaces -> Phone Port -> Calling Features -> CallWaitingEnable = uncheck all boxes


Even with no other phones as forwarding phones in google voice; callers will likely still hear ringing for 25 seconds from google voice before going to voicemail.

A second way is *56  (Enable Call Waiting) and *57  (Disable Call Waiting) from the hand set.

I can confirm these work with GV on an OBi202.  

See here for other * codes, not all of them work with GV.
