Extension phones not working after fibre installation

[purplesupersue]

I had fibre installed last week, now two of my four phones do not work.  They are all panasonic, the two that work are one set and the other two separate - but all worked before fibre.  Any ideas?

Once a property is supplied with SOGEA broadband, internal extension sockets no longer function because no PSTN service is reaching the address.

You'd need to have all the handsets working off the base-station which is plugged into the Sky Broadband (or Max) Hub

Hmm, well the two phones on one set work together - only one plugged into modem, maybe I need to get a new set of four linked phones?

That's correct, yes.
