Hi,

I have registered for sipdicount.com and until last week was able to make calls with the service.

This week, I have started to experence some problems.

When I call a phone number, the person's phone rings, but I don't hear a ring tone. When that person answers the phone, I can't hear them and they can't hear me!

Has anyone else experenced this problem and if so, how did you go about fixing it? My phone is behind a NAT router, but I didn't need to forward any ports last week, so I don't think that could be the problem.

Thanks, Paul.

Have you tried using sip1.sipdiscount.com proxy.

And use a stun server?

The the problem you describe sounds like a codec problem, try ensuring G711A is used.

It can be a NAT problem, but as it worked before would seem strange.
