I use an ObiTalk device with Google Voice. For E911 service I have an account with Anveo that I've configured through ObiTalk. But something is preventing my Anveo E911 service from staying online ever since I replaced my TP-Link N300 (TL-WR841N) with a TP-Link AC1750 (Archer A7) router. Now I get emails from ObiTalk indicating that my service is no longer registered. And email notices from Anveo indicating my E911 service is offline. But about 20 minutes later I'll get another set of emails saying all is good. And 20 minutes after that a new set of emails saying everything is down again. And it repeats over and over and over. I know there’s a conflict somewhere so I investigated the OBI Expert Configurations and realized that instead of connecting to the Anveo servers, it’s trying to connect to my Disney Circle filter device. I confirmed this is the problem by turning off my Disney Circle and rebooting my router to delete the Circle as a DHCP client. I reconnected to Anveo through ObiTalk and everything worked – my E911 service was intact. Unfortunately, the problems resumed as soon as I reconnected my Disney Circle. There has got to be a setting on my new router that is confusing my ObiTalk device into trying to connect to my Disney Circle instead of Anveo. But I don’t know what it is or how to fix it. Any suggestions? Anveo customer service has no ideas. And ObiTalk tells me to make sure certain ports are open.... Not sure how to do that.
