I have no dialling tone on my landline

No dialling tone so unable to make or accept any calls

@Gill01 Is you landline phone plugged into the back of the Sky router?

@Gill01  When was the last time your landline worked?  Have you upgraded your broadband service recently?

[Gill01]

Two weeks ago .. only difference is I removed my sky box as I do not have sky and haven't done for a year 

but no wires were for the telephone as that was already in my hub

@Gill01 If you do not have sky, then where was the telephone connected too? Sky take over the line when you have SKY Broadband as they are your ISP.!
