If somebody keeps ringing who you do not want to hear from, you can block their number in Mucka. Your receptionist will not answer them. They hear "Sorry, nobody can take your call" and the call ends, before the receptionist starts, so it uses none of your minutes.
Why blocking them on your phone is not enough
When your phone blocks a number, it turns the call away, and your network treats that as your line being busy. If your phone forwards calls to Mucka when you are busy, that blocked call is forwarded straight to your receptionist. So the block on your phone sends them to Mucka instead of stopping them. Blocking the number in Mucka as well is what stops them.
Block a number from a call
Open Receptionist, find their call under Calls and open it. Tap Block number (on a phone, Block this number at the bottom of the call). The button changes to Unblock, so a slip is one tap to undo.
Block a number by typing it in
Open Receptionist, then Settings, then Blocked numbers under Answering. Type the number the way it shows on your phone, like 07700 900123, and tap Block. Every number you have blocked is listed there with the day you blocked it, and Unblock next to each one.
What you will see
Calls from a blocked number still appear in your Calls list, marked Blocked, so you can see they tried. You do not get a missed-call card for them.
What it cannot block
- A withheld number. There is no number to match, so a caller who hides theirs is answered as normal.
- Your own number. Some landlines pass your own number along on every forwarded call, so blocking it could stop every call reaching your receptionist. Mucka will not let you add it.
- Texts. Blocking stops calls to your receptionist. Texts are not forwarded by your phone, so a text from that number still reaches your own phone, where your phone's own block deals with it.
