Using intervoip's web interface, I used the call feature to call my house phone and then another call (relatives in egypt at the moment)

I ended the call and rang back but something went wrong, The call on the web said ended but it was still and still is ringing on my landline, its not ringing egypt, just this very bad ring as it normally does, its been going on for about 20mins now, and i don't know how to clear it off the line, i have tried pressing 'r' and all them, but still nothing.

Any ideas?

Thats strange, i have just tried again and its clear

hmm

Thanks for looking anyway

Yeah, has a time-out usually of around 20 mins.

If you find the call on your line is still connected and hanging up doesn't clear it then:

With the handset picked up press the Recall button.
Wait a few seconds.
Put the phone down.
The phone should ring back.
Pick the phone up.
Wait a few seconds.
Put the phone down.

The line should now be cleared.

thank you, i will give that a go if the problem happens again.
