SIP Trunking

SIP (Session Initiation Protocol) trunking refers to a VoIP service that allows a business to connect their current PBX system to a cloud-based phone system using an ITSP (internet telephony service provider) such as us.

What does PBX stand for? Private Branch Exchange (PBX) is a private telephone system used within an organisation. It allows users within the organisation to manage incoming and outgoing phone calls.

Business VoIP service provider Voice Carrier has revealed that the company’s own IntelliSIP product is now compliant with Avaya’s IP Office.

U.S. company Ipsmarx released an SIP trunking service earlier this month allowing service providers to relieve complexities that exist around routing and billing management, expand income potential and cut down on expenses – all simply by using a lone turnkey system.
