Well, fun with OFCOM.
We are trying to get 07 numbers as we have mobiles. Customers want 07 numbers! They would rather not confuse the hell out of people giving them an 01/02/03 number, but more importantly so they do not have to pay for incoming calls to the mobile. An 07 number would allow incoming calls to be received for free like other mobile operators.
OFCOM should give us 07 numbers as we are are operating a mobile network (albeit the vast majority subcontracted to 3). We route calls to and from mobile handsets. Simples.
Guess why they won't give us 07s?
They say that we would put 07 numbers on a SIP fixed handset. I have no idea where they get that idea. We have no plans to allow 07's to be assigned to anything other than SIM cards. Yes, we will allow various call diverts as you would expect, and like other operators so, but not assigning an 07 to a fixed SIP handset alone.
What is interesting is that they are saying that if any call could fail to go via wireless telegraphy to/from a mobile device then that is not a mobile service and so we cannot have 07 numbers. Reading the numbering plan, it does indeed say that every call has to be from or to a mobile.
That is interesting. I can't see orange's 07973100150 customer service number going to a mobile - it clearly goes to a call centre (not picking on you orange, all the networks have such numbers). And I think every mobile operator allows a divert on out of coverage option which means calls do not go to/from a handset in those case. Sounds to me like they either need to correct their rules or revoke all 07 numbers in the UK!
I'm waiting for their reply...
