Hey there, welcome to the forums,

You state you have a DSL 512 service - is that shared between PC bandwidth as well as your ITSP ( Vox )?

If you run a speed test via http://www.speedtest.net check to see what your upload/download speeds incase it isn't as good as it should be.

When you receive a call via the FXO is it good both ways ?

If you go to http://epygiip/generalconfig.cgi and tick the "Accept stray SIP requests" box and save, does that rectify your problem ?

Regards

Kevin

Thanks for the quick response
Yes I use dsl for both PC and Voip (not much PC traffic)
Ticked "Accept stray SIP requests" still the same
Speed test : Download 0.77 and 0.67 mb/s
Upload 0.14 and 0.13 mb/s
ping 420 and 370

Hey mate,
What sort of modem are you using?
Does it have a firewall?
You can try a "DMZ" to the Quadro's ip address if it does or set the modem into bridge mode and let the Quadro do your logging on.
