I have an Obi100 and a Obi100 connected to my home router (RT-AC66U). I use one for work and one for the home. I had both configured to use different Phonepower accounts. That caused the Obi devices to reboot and drop calls. I've since reconfigured the one Obi110 to use Google Voice and no longer have any problems.
However, the second Phonepower account is paid for and I'd prefer to use it if I could get it to work. I believe having the two Phonepower accounts coming into the same router was causing the problem and I'd like to think there's something I can do with either the router or the Obis to get both peacefully coexisting.
Personally, I believe this is a Phonepower issue and I just got off a chat with their Support. They blew me off and told me that their service can't cause reboots and I should contact Obihai. I told them that both my Obi's work fine if only one of them is connected to Phonepower. "Contact Obihai".
So, I turn here for help...
