I am in the UK and have imported a telephone from Germany called "Senao". My problem is the out going volume is very low and who ever'I call can not hear what I am saying. The incoming volume is also low but that is not so much a problem. It is a cordless telephone system. Does anyone know if there is any way of boosting the out going volume on the telephone line?
I hope someone can help. I have tried different Senao models all with the same result
Thanks in advance
