So I have new OS7100 ver. 4.99 install that I've noticed doesn't automatically reconnect to the ISP 1 SIP carrier after a reboot. I always have to disable/enable to reconnect. I have DNS in place in 5.2.13 SIP carrier options. Wondering if I should also have DNS in 5.6.1? Currently default at 0.0.0.0. I've searched this forum and some people mention a Multi DNS option? Can't find that option anywhere unless just adding DNS in 5.6.1 is what they are talking about.
