I regularly chat with a friend via Face Time on the other side of London from where I live.

Works beautifully with amazing clarity (have chatted with other friends overseas too with equal amazing clarity).

My question is, I can call up my London friend any time but she is unable to call me herself? She has tried checking all sorts of settings but doesn't seem able to solve this problem.

I'm the one with the iPad and her with the iPhone.

Any ideas folks?

Thanks.

Is she dialling your Apple ID email address which will be being used as your Facetime 'Number'? It may be that she's dialling your phone number (assuming you're listed in her Contacts with both your email and phone number in the same entry) instead of the email address, therefore it isn't getting to your iPad.When she chooses to Facetime with you, she should choose this email address instead of your phone number.

Supposedly this confusion will be removed when iOS6 comes along as Apple will merge phone numbers and email addresses into a unified Apple ID.

Thanks Tom.

Which of my email addresses should I advise her to use to contact me? My hotmail one or my bt one or the one iCloud gave me called........@me.com?

It's the email address associated with your iTunes account which may not ne your icloud one.

On the contacts page, the facetime button will have a little camera symbol next to it to signify it can be used.
