Thanks Mick,
I tried doing what you said, and it still doesn't work, the only thing i can think of is that last night, my hubby rang me from home as i was out, and when i came in i noticed he hadn't switched the phone off, (he didn't press the green button to end the call)and it said on the screen; 74 mins! so i am wondering if that has anything to with it? like i say, i can get incoming calls, and i can ring out on the other extention line, i have tried unplugging it a couple of times today thinking it may re-set itself, but obviously it hasn't!
It's so frustrating as i have to take the other phone round the house with me now if i need to make a call! nevermind, i will see how it goes, maybe i need a new phone altogether, as i have noticed the power in the the phone doesn't hold for as long as it should do, Thanks anyway, Jane.
