SIP A Session Initiation Protocol (SIP) connection is a VoIP service - offered by many Internet telephony service providers - that connects an organization’s private branch exchange (PBX) telephone system to the public switched telephone network (PSTN) via the Internet.
SIP is fast becoming a cost-effective way to allow calls to flow to and from your business. In the same way that Easy Telephones can aggregate PSTN services to your business we are positioned to do the same for SIP. Cost effective and simple to deploy, SIP is a means to allow your business the flexibility it needs for its unique calling patterns.
