Hi

My wife was dialling me on her mobile to see where I was when I hove to in site, so she cancelled the call. However, my phone started ringing from her number and wouldn't stop no matter what button I pressed until I switched the phone off.

It was like her call had caused my phone to ring but in ringing off before I could respond, it set off an infinite loop of ringing attempt to respond, no response possible, therefore no way of shtting off the ringing.

We both use Nokias on the Orange network.

Any ideas how this could have happened, how it could be done deliberately and what might be done to prevent it?
