for some reason, and although i have registered my SIP account in my Zoiper on my Windows 8, Lumia 920 smartphone, when i call my VOIP number(from a landline), it does not ring on my mobile.
It says, "registered" and "available", which means it is ready to accept calls. But, when i call from a land line, i hear no ringing neither the phone rings.
I have an X-Lite installation on my Windows 7 PC for testing purposes, and it works like a charm...
Can you please help me with this?
Many thanks in advance.
