Make the move now to SIP because ISDN lines are being phased out starting in 2020!

SIP trunking is an alternative to ISDN phone lines. ISDN is being discontinued starting in 2020 and carries a substantial recurring cost to any business. SIP works by transferring your voice communications over fibre optic cables (over the internet) improving call quality, reliability and significantly reducing costs by on average 80%. Our calculator below will provide an outline of your predicted yearly savings in Great British Pounds (£) by switching from ISDN to SIP.

Simply fill in the form below.
