Phone Lines

In business one of the larger figures on the P&L statement often is telecommunications. Your aim is to keep that figure very low, while being able to be productive.

To understand how to keep the costs low, you need to first know the different types of telephone lines that are available.

The Plain, Old Telephone Service line (POTS line) is the type of line most people use at home. This line is delivered to you via an analogue copper wire which is still owned by Telecom. It lacks essential services that business requires. One is multiple phone numbers associated with one phone line. Multiple phone numbers per line enable businesses to have a direct dial-in number (DDI number) so a call can reach the right person. This makes POTS the most expensive service on the market.

The digital lines that were created for businesses also utilize copper wires. They use a standard called ISDN. ISDN allows more than one call through single copper wire. There are two options – basic rate service, allowing two calls per line (basic rate ISDN) and primary rate service allowing up to 30 calls per line (primary rate ISDN). This service is also mostly available from Telecom, and is as expensive as POTS lines, except it does have all the business services.

The new competition to the old Telecom services (described above) comes through the digital lines that utilize data connections that are also capable of delivering the Internet service to you.

SIP Trunks

Session Initiation Protocol (SIP) was created to enable voice connection to be established over a computer network. It has now been established as the industry standard for delivering phone lines via a data connection. A phone line that is delivered to you via a data connection using SIP protocol is called a SIP Trunk.

SIP trunks deliver outstanding savings compared to a traditional landline plus internet connection set up. When you get a SIP trunk, the supplier doesn't need to pay traditional telco for the landline service.

SIP trunks are high quality phone lines comparable in quality to business grade ISDN lines. Typically a SIP trunk provider delivers both data and voice over the data link to the business premises, controlling the quality of service end to end. The voice stays within the provider's network. Even though SIP trunks use the same Internet Protocol as other VoIP calls, SIP trunks differ from VoIP because they don't typically go over the internet.

There are many SIP Providers generating stiff competition, so you can negotiate great cost savings for your business.
