SESSION INITIATION PROTOCOL

In the era of electronic messaging, it’s still good to talk - but businesses persisting with traditional phone networks for their voice communications face crippling inflexibility and exorbitant line rental and call costs.

Complex inbound and outbound call processes are virtually impossible with these traditional networks, which restrict the adding and removing of DDIs or the introduction of even semi-intelligent routing protocols.

SIP (Session Initiation Protocol) technology provides the answer allowing you to upgrade your voice telecoms set-up, while eliminating scalability concerns and removing the costs of traditional line rental and voice infrastructure - such as PBX equipment.

Put simply, SIP enables more cost-effective access to the PSTN, opening up new capabilities like call routing and fax. This gives you greater control over numbering, as well as providing the all-important flexibility that allows your connectivity to grow with your business.
