OFCOM have made it very clear to us that because a call to a mobile number could be picked up on a fixed SIP handset, we cannot have a block of 07 numbers.
They have pointed out that the 07 mobile numbers have to be used for a mobile service which is defined as :-
‘Mobile Service’ means a service consisting in the conveyance of Signals, by
means of an Electronic Communications Network, where every Signal that is
conveyed thereby has been, or is to be, conveyed through the agency of Wireless
Telegraphy to or from Apparatus designed or adapted to be capable of being used
while in motion;
The fact that a call can be answered on a non mobile device is enough to block our application.
But this definition effectively blocks all use of any sort of divert on mobiles to a non mobile handset. It means that the calls to your 07 mobile number might not use wireless telegraphy to/from a mobile device, and the rules are clear that every signal that is conveyed has to.
I can only assume we'll get the announcement from OFCOM soon that they are banning the use of call diversion services on all UK mobiles (other than diverting to another mobile) so as to ensure they treat all operators equally. Anything less would be unfairly treating one operator differently to another, which I am sure OFCOM would not wish to do.
