Can someone (hero) from this forum post the link to most current firmware for OBi5xxx, I believe it is 4.05 (Build 5903EX) TIA.
I suggest that you fill out the form below, being clear that this is for an OBi 504/508vs, and they'll probably help you get the current firmware.
https://www.obitalk.com/info/support/supportTicketFormI have submitted several tickets. They go into a blackhole.
The 50x devices don't work with google voice. The latest advertised firmware (4.0.4 Build: 5793 from Jan 2018) will register with google
but generate 500 error. I noticed that the 200 devices show up as an additional forwarding phone (Obitalk)
in google voice settings, but not so for 50x device.
It seems the horrid support is now even worse (now that Polycom took over). I have a six month old device that should be under warranty and eligible for support. Phone calls to support go to voicemail that won't be returned and support tickets go into a black hole.
Kind of a bummer. They are the only game in town for GV, and they won't let us play with the ball.
