Has anyone else had any issues with the SPA122 not wanting to play nice with 2wire modems? We started to deploy the SPA122 recently and there seems to be a particular issue with our customers who have 2 wire modems, like the AT&T/2Wire DSL modem/router combos. We have successfully deployed the SPA2102s with these modems/routers in the past. We can't get them to work with the SPA122 at all.
