Hi,

I think there may be Asterisk (and FreePBX is just a wrapper around Asterisk) is sending OPTIONS messages. These messages were being rejected by some enhanced security we put in place.

The "qualify" setting turns this "feature" on: http://www.voip-info.org/wiki/view/Asterisk+sip+qualify

The problem here is that we need to authenticate these messages. This is going to take some more investigative work to resolve. In the mean time, I have relaxed this particular security setting.

Thanks for your help in this matter.

Regards,
Norm
