I'm using Comtrend CT6382T-1 for my voip phones with another Voip provider and it works great. But when today I bought a number and I tried to use it with freephoneline I was very disappointed - I can make the outgoing calls,
but I can't receive any incoming calls

I hear just the tones like my phone is diconected.
Btw it works fine with the free software from freephoneline for the incoming and outgoing calls.
I didn't find any specific information about the voip settings for my modem+router in internet (I tryed all that I found in the settings of my Comtrend) and i'm very surprise that it works with another provider but not with freephoneline.ca.
Anybody can have an idea about that
