The latest available firmware for OBi100 and OBi110 is 2886 which is clearly less then 4464.
Does it mean that the OBI110 will no be able to connect?
The last and correct version of the firmware for the OBi 1xx series was 2886.
The newer generation, 2xx series have a different firmware with different version numbers. The firmware is not interchangeable.
Connect to what? You can still use a OBi 1xx device with ordinary SIP VoIP service providers. You can't use it with Google Voice.
I am in US having Obi202. I connected it via OBITALK to OBI110 which is in a different country (and connect to a local provider via the line port). In the last 10 years I was able to dial overseas number in the local rates. ALl this stop working (even the OBI110 is green). When I try to dial or to connect to the remote OBI110 I get a message: "the number you dialed XXXXX was rejected by the service provider reason 404"
I restarted my router and the obi in both sides but it doesn't solve the problem.
