Yes as signal is poor for my mobile but I don't ring out on it as it costs a lot.
I message my children and if they want to chat they ring the landline (they all have unlimited inclusive minutes so it doesn't cost them a bean extra) if I'm out and need to ring DD2 at home (she lives with me at present) I phone the landline as even her phone isn't that reliable, though it's much better than mine! (I have inclysive minutes too)
If I need to actually ring someone whilst at home (only ever ring companies or surgeries or council or whatnot, never personal) then I say, "it's such a bad line, I'll ring you back on landline" and they invariably say, "oh no, you might not get to me, I don't have a direct line to give you, give me the landline number". If they don't, I play the old gimmer line," oh dear the handset isn't in its cradle, can you ring me? I have no idea where I've put it but if you call me I'll hear it ringing!
