The full potential of the ISDN replacement market (ISDNoIP) can only be unlocked if certain preconditions are met, according to Stripe 21 MD Steve North.
ISDNoIP leverages new technology to drive down costs by up to 40%, but only if it is delivered with the same guarantees as the established 20CN ISDN technology it replaces, noted North.
Anything less than 20CN ISDN levels of reliability will only lead to failure, he believes.
"Reliability is crucial to sustainable, recurring revenue," he stated.
"When selecting a ISDNoIP supplier it is crucial that they offer a SLA which exceeds 99.99% availability. Similarly, the ISDNoIP service must be fully managed end-to-end as standard."
North also believes that Ofcom's uplift of 74% in CPS charges plays into the hands of resellers wanting to side-step the margin squeeze and potential CPS price war associated with the watchdog's attempt to encourage resellers to adopt a SIP and hosted strategy, which also raises security and reliability issues if the system relies on the Internet to carry part of a call.
"However, leveraging a ISDNoIP service bypasses CPS and offers guaranteed quality of service," added North.
He argues that the upsides of such an approach are undeniable, citing the benefits of no change to existing telephone numbers or customer CPE, and therefore no additional costs to the customer.
"Number porting must be seamless and transparent, and one-off setup costs must have the option to be amortised over the contract term," added North.
"There is also no risk of losing the customer as a result of migrating to the new service. ISDNoIP should cost no more than £8.00 per month per channel and be cost-effective from six channels upwards, either ISDN2e or ISDN30e. This vastly increases the reseller margins on both rentals and call charges, but requires zero effort from the customer."
To motivate the market for ISDNoIP Stripe 21 is offering a free ISDN30e installation to all new and existing resellers on orders placed before 30th June 2014.
