 Line Rental

IBSTec’s portfolio includes wholesale line rental (WLR3) for BT PSTN and ISDN lines, enabling you to provide customers with high quality, reliable BT lines at competitive prices for voice calls and/or broadband. If you already provide a customer’s broadband service, securing their line rental business as well further cements your customer relationship. Even where your customers already have their lines installed by BT Retail or any other BT Wholesale based service provider, you can still transfer those existing lines to us and continue to benefit from the revenue they generate in terms of the rental and the calls made on them. With just a 30 day cancellation period and no minimum contract terms, they provide a recurring monthly commission for the life of the connection. Flexible billing options allow for white label branding while a choice of 3 line care options for faults and maintenance are also available. IBSTec PSTN and ISDN lines are maintained by BT Openreach.
