ISDN30e lines come with a minimum of eight channels. Each channel allows one concurrent external phone call so four calls in and four calls out would mean you cannot make or receive any further calls until a line becomes available. If you don’t need eight concurrent conversations with the outside world then your choice would be multiples of ISDN2e.

You can have multiples of ISDN30e circuits if your telephone system supports them and is how larger offices handle their calls. We will save you money when we take over your ISDN30e lines and that is a promise; it only takes 15 days for the line transfer to complete and you will get 24/7 support 365 days a year. Call us today FREE on 0800 027 8888. The installation process for new ISDN30e circuits take a little longer than ISDN2e or analogue lines and you must allow a minimum lead time of 30 days. Pease bear this in mind when you are planning a new system. Call us to discuss your requirements on 0800 027 8888 or request a call back below.


What our clients say about us

It’s not very often that as a company we feel inclined to write to our suppliers, other than occasions where problems have occurred, but in this case we feel it right to make an exception.

We want you to know that we have been very impressed with the quality of the service your company has provided us to date, in particular we appreciate the responsiveness and professionalism of your engineer Bryan Elsworth, without which we would probably not have made the switch from BT.

Please pass on our thanks to the staff, they have made the transition as easy as we could have wished and gone the extra mile to make sure we are fully up to speed on the new set up.

We look forward to doing business with you for years to come.

Chris Hawley - Auto-Lift UK Ltd

I wish to recommend the services of Brian Elsworth of Z1 Telecom. He has shown himself to be industrious, knowledgeable and helpful with regard to the installation and maintenance of our telephone system.

To whom it may concern.

I would like to may it known that we have received 1st class service from Z1 Telecom and Bryan Elsworthhave been superb. Whenever we have requested help they have always been willing to help over the phone or, if requested, they find the time to make a call out.

After poor service in the past from other telecommunications companies it’s been a pleasure to find Z1 and we are more than satisfied with all aspects of the company.

Thank you.
