I had a lot of problem trying to get it right, and ISP were quite ignorant at this. Eventually it was like I conquered Mount Everest! Use most default settings except server, username and password. The additional setting was to add server as secondary server as well.
Hi. I am with Axxess and have used a B315 router over LTE for internet and VOIP services, using the analogue RJ11 port for the telephone. Now I have upgraded to Fibre and am using a Huawei B618 router and want to configure the VOIP with analogue out as well, but need some help with the settings.
