I think the deal is that you register numbers with them - they call them with
a secret code to prove you control them. Those are your 'verified' numbers.
You can then set those numbers as your outgoing CLID. There's a setting in
the app, or a field you can supply to your SIP client.
Some of the Betamax brands also have local access numbers. You call those
numbers from a regular phone, and if the CLID of that phone matches one of
your verified numbers then you're allowed to dial an onward number and the
call is billed to your account, and the ongoing CLID shows as that number.
Not all brands support this.

+441133550251 should work for both incoming and outgoing calls.

It appears those dial-in numbers when called forward to another number, with
the forwarding charge billed to your Betamax account. So you can use them
for example to have a landline number that forwards to your mobile.
I'd guess you can configure them to call a phone number like your landline
or mobile. You then pay the Betamax per-minute cost for calling that
number. It's possible they also ring the SIP phone which is registered with
them for outgoing calls - not sure if that also works.
