With SIP intelligent devices communicate directly with each other over a simple transport infrastructure. This contrasts with the traditional telephone network, where transport between dumb endpoints is provided through an intelligent network core. This difference allows the network to become a commodity and allows any device attached to the network to provide a service to any other.
Migrating to SIP trunks removes many of the geographical and functional restrictions of traditional ISDN and analogue lines. It can also enable you to converge your voice and data connectivity through a single service or if required, split this service over multiple circuits to remove any single point of failure.
SIP Trunks deliver greater flexibility, scalability and business continuity while reducing your on-going communication costs.
