What do you mean by service provider though?
I understand Ofcom terminology to refer to three parties: OCP, TCP and SP.
1. The Originating Communications Provider is that on whose network the call is originated.
2. The Terminating Communications Provider is that on whose network the call is terminated.
3. The Service Provider is the organisation whose services are accessed by the call.
These terms are used when revenue sharing is involved.
The SP is a customer of the TCP. The caller is a customer of the OCP and the SP.
Where the service is designated as a "premium rate service" the SP becomes a communications service provider and thereby falls within the scope of Ofcom's regulatory powers (subcontracted to PhonePay Plus).
With 0800 numbers called from phone boxes, the supplementary charges may make the SP a customer of the OCP.
Please correct me if I have this wrong, although I make this posting with some confidence.
