SIP Trunk- scaling business technology framework with IaaS

Session Initiation Protocol (SIP) is a way of making phone calls over an IP-based technology using traditional PSTN numbers. It has emerged as a universal standard for the next age IP-based voice solutions. SIP enables users to engage in integrated communications from anywhere irrespective of the underlying network infrastructures used.

The universally available access to the Internet has brought in the age of SIP-based trunking services that allow businesses to move from dual and physically separate voice and data networks to an integrated and converged all-IP infrastructure.

The migration to SIP-powered IP phone system has given more advantage to the organisations adopting it as it also paves the way towards Unied Communications. SIP seamlessly enables and integrates email, text messaging and chat on a single platform.
