How do SIP Trunking and Hosted Voice fit together? To understand that let’s look at the definition of both.
SIP Trunking can provide applications such as voice, video, desktop sharing, web conferencing and shared white board to name just a few. Basically, SIP Trunking is a method of sending your voice connection over an existing data line, broadband or the internet.
A SIP Trunk provides the same service you get from traditional analog phone lines or a channel on a PRI (Primary Rate Interface) circuit. The difference is, instead of being a physical wire, a SIP Trunk is a “virtual” phone line which is provided by a SIP trunk provider. Actually the provider uses your data circuit, cable modem, or Ethernet over copper or fiber to connect your phone system to the Internet.
A form of business known as Hosted Voice services is where the Hosted Voice equipment, servers and services are hosted by the IP provider. The Hosted Voice IP provider manages calls and routes them to and from the subscriber's existing telephony system and equipment. Hosted Voice is also frequently referred to as managed Hosted Voice and can save companies from the potentially expensive costs of having to invest in VoIP equipment and manage their own system.
All Hosted Voice switching gear is located at the IP provider’s facility and only the IP phones are at the customer premise. The ability to provide this Hosted Voice service keeps the customer from dishing out a lump sum of money as a Capital Expense. Actually it becomes an Operational expense as the service is billed on a monthly recurring basis. Depending on the length of the agreements the customer gets a technology refresh with each renewal contract.
Hosted Voice is also sometimes referred to as putting your telephone system in the cloud. The majority of phone system manufacturers are providing new and upcoming products that allow SIP to integrate directly into the telephone gear via SIP licenses. This is a tremendous cost savings as having to purchase, CO Trunk cards or PRI interface circuit boards for basic legacy digital phone systems.
In summary, the SIP Trunk and Hosted Voice solutions provide all the features and more that the legacy systems are providing today. The difference is “at less the cost”. Contact your local IP provider today to find out exactly how much you’re entitled to save by converting to SIP Trunking and Hosted Voice IP systems.
