Our phone switched over to digital last year but for some reason unknown it’s now got a constant engaged tone. I have looked through lots of posts which don’t ever give a proper answer just suggestions which listed below I have tried.
So far I have powered down the hub for an hour.
Checked 1571 in case of answering machine, but as it’s just engaged tone it won’t dial it.
checked the phones aren’t set on multi.
If there is anything else I can try please help!!
