Save on lines and calls by moving to SIP

STL can often reduce your overhead costs by reviewing your line usage and call traffic to make sure that you have the correct number of lines that your business requires and that they are being used effectively.

Moving from ISDN lines to SIP trunks can save businesses up to 70% on line rental and reduce call costs by using your data connection for voice.

STL offers highly competitive rates, flexible contracts and inclusive call packages on lines from carriers such as Gamma and BT, including local, national, international, mobiles and calls to non-geographic numbers.

Alternatively, STL is still able to provide more traditional analogue and ISDN services through our wholesale BT OpenReach relationship.
