[asterisk-biz] Termination to 44780, UK Premium?

A [very] simplified version of the UK numbering plan is:

+44 1 & 2 : Normal landline numbers
+44 3 & 4 : Not used at the moment
+44 500   : Tollfree
+44 55 & 56 : Numbers for VoIP subscribers
+44 70 : 'Personal' Numbers - designed for forwarding to other phones, costs 
between GBP0.1 and GBP0.5/min
+44 76/77/78/79 : Mobile
+44 800 & 808 : Tollfree
+44 844/845/870/871 : 'Shared cost' - mainly business contact numbers, 
retail cost < GBP0.10, but more expensive than most people pay for a 
landline
+44 9 : Premium. Up to GBP1.50 per minute

A lot of international carriers classify +44 8 anything as either premium or 
mobile and charge a high rate or block it.

If these numbers are important to you, it might make sense to terminate 
these on a UK carrier - we can do this for you, but do need wholesale 
volumes and so you'd probably have to send us some other traffic too. If you 
are interested, drop the team at sales at magrathea-telecom.co.uk a line.
