What calls and lines do 4Com offer?

We offer a selection of services in terms of calls and lines, including ISDN2e and ISDN30e lines.  ISDN stands for ‘Integrated Services Digital Network’ and these lines offer an array of extra benefits. One of these is CLIP, which allows you to see who is calling you before you answer your phone.

ISDNe2 is a high-performance service which delivers high-quality voice recognition and an extremely reliable data transmission. ISDN30e is ideal for business telephone lines, as it provides data services for those needing at least 8 phone lines.

At 4Com we also provide SIP and SIP trunking, which is a reliable and cost-effective voice service that is more flexible than ISDN. If you’re interested in finding out more about SIP and SIP trunking, please click here.
