ISDN

Excell Group: Cloud Communications / Solutions / Voice Solutions / ISDN

With our ISDN bundles you’ll receive a best-fit, competitive Calls and Lines solution to help you minimise your overheads.

Our packages offer significant telephony savings compared to other providers, with a choice of call minutes packages and line types, including ISDN2 and ISDN30, to suit your exact requirements.

Each ISDN package includes a generous allowance of call minutes, line rental, DDI number rental and inclusive features. And you’ll only pay for what you use, with no minimum spend and calls rounded down to the nearest second to help keep costs under control.

The process of migrating to our Calls and Lines services is seamless. This means no engineering changes or site visits, and avoiding any associated downtime. We’ll take care of the whole transfer, which can be completed in as little as ten working days (subject to your existing provider of course!)
