What is SIP trunking?

Your voice and data connections are vital components of your business - but so is the cost of running multiple lines, their flexibility and how much control you have over them. Telefonix provides a flexible and low-cost alternative to ISDN for inbound and outbound voice calls. This factsheet will highlight the benefits of buying Telefonix’s SIP Trunks.

SIP Trunking supports business continuity

SIP trunking offers a flexibility that is not available with traditional ISDN. A number of possibilities can affect how resilient your voice and data connections are. Unforeseen circumstances - such as damage to lines, moving offices or being unable to redirect calls, can be damaging to your business. SIP trunking minimizes these problems and ensures you can keep working through every eventuality.

Number Flexibility

SIP trunking supports your business by allowing you to decide which number you want to display on a call-by-call basis. Even if you’re making a significant move in location, or just wanting to grow your business without opening more offices, SIP trunking allows out of area geographic number ranges to be used. This shows your business as local, despite being physically located elsewhere.

SIP Trunking saves you money

Why have a separate voice and data connection when you can have both on one line? By discarding any unnecessary ISDN lines, you will be able to save a large amount of money. In addition, SIP trunking can typically save you a further 50% on line rentals and 25% on calls. By utilizing the benefits of SIP trunking number flexibility when you’re moving office, you will not need to spend money on changing stationery, advertisements or listings. SIP trunking also allows you to make free calls between connected sites, even internationally.
