It's been a while since I've been on these forums. So much so, my old account no longer worked. I have ran an PIAF/IncrediblePBX system since 2012 with this this type of setup with no problem until recently my system decided it wanted to retire. Yes, I have a backup but not sure I could figure out how to restore. Anyways, I'm trying to start from scratch with the latest version of Incredible PBX 13 and can't get this to work. I've updated my accounts to the OAUTH. Not sure if this has anything to do with my problem. I have three Google Voice accounts (for explanation, we'll call these Account01, Account02, Account03). Account01 = Main PBX number. When you call this number you get the IVR. Account02 = Fax. This number goes straight to HylaFax for Inbound/Outbound faxing. This part works just as it did in my Incredible 3 system circa 2012. Account03 = This routes to extension 701 and rings my physical Nortel VoIP phone. I also use this account on my iPhone as it is my main phone number. I use the GoogleVoice app on my iPhone. When I have Account03 registered and connected in Incredible PBX, it will ring extension 701 as expected, but never simultaneously rings my iPhone. Once I've logged out of the account from the PBX it begins ringing my iPhone again. This always has worked in the past. Curious if something changed or maybe I don't have it setup correctly. If there is a better way to handle this I would appreciate any assistance. I like this system because if the PBX was done for whatever reason, I still received the call on my cell phone.
