4Sight SIP Trunks
The cost-effective and flexible alternative to ISDN
As a Gamma Gold Partner, 4Sight provides SIP Services that offers a highly-flexible alternative to ISDN. With our SIP Trunks you get a service that is more robust and cost-effective than ISDN. Our service can support connections ranging from two channels for businesses with small PBXs, with no limit on the number of channels that can be supported for large enterprises and contact centres.
Compared to ISDN, SIP Trunks are cheaper on a per-channel basis and more flexible in terms of what telephone numbers you can have and the locations in which you can have them. In addition, they are quicker to install and offer a robust business continuity service that ensures your business never loses any calls.
The benefits of moving to SIP trunking can transform business communications and the process of switching is simple and safe, even for the most risk averse of businesses.
