How will 21CN affect my telephone line?

We had an enquiry from a customer this morning:

“I am persistently being contacted by David from ***** who has advised me that with 21CN BT are changing every business line from Analogue or ISDN to a SIP network and that there is no choice in the matter”.

David was trying to get the customer to move to a SIP service by telling her that she would need to do it soon in anycase so she might as well preempt it by doing it now. As a SIP provider I am not averse to selling SIP services but this has to be approached ethically.

From the customer’s perspective BT aren’t getting rid of analogue lines or ISDN. What they are doing is changing the connection at the exchange so that all calls will run over voip between exchanges. This will make the network more efficient/cheaper to run and potentially allow for the introduction of new features in the future.

So any kit the customer has should still work and they will still be ordering new lines as they do now. They needn’t worry about having to re-equip their office.

Potentially there will be new products such as the ability to order broadband and voice as a single line. This is effectively what LLU operators do today though some may sell it as a free broadband line (comes with notoriously “cheap” quality and customer service etc).
