how to dial to voipuser when someone is sending a fax?

I am completely new in this with voip fax, so I would like to know how must someone dial to my new 070xxxxxxx number from outside the united kingdoms, when sending a fax to me?
also I am not sure if it is wrong, it asks me the destination, and I put Israel, but didn`t put a number in cause I have no fax machine, because of this i need it that people can sometimes send me a fax, and right now I am in need of it urgently.
Please help.

The info on how to set up calls from outside the UK is covered in this FAQ ...

To use the fax service, just go to 'My Sip Account' and set up a new number just for fax traffic. Click on the number to edit it and set Destination one and Destination Two to FAX using the radio buttons.

Any incoming fax will be sent straight to your email address, this will not affect any simultaneous voice traffic since that will be on a different number anyway.

thnak you gray, for your response, now I understand, it is easy actually.
it is an eccelent help here, thank you.
