What is a SIP trunk?

A SIP trunk can be thought of as a telephone line which is created from spare bandwidth on your broadband or data circuit.

Do I need to buy a new phone system in order to use a SIP trunk?

Most up-to-date systems will have the capacity to support IP telephony. However, if your current equipment doesn’t, Tipicall can fit a conversion unit for you.

Why do I need a SIP trunk?

With cheaper running costs, cheaper call charges and improved flexibility (virtual numbering will allow you to operate from wherever you like), it makes sense to invest.

How reliable is SIP trunking?

SIP trunking is as reliable as the circuit on which it operates.

What’s the catch?

Problems may occur if you have only a single circuit which all your voice services run over. As with traditional ISDN30 lines, failure of the circuit may result in loss of all service. However, tIPicall provide full engineering support for your network to ensure maximum resilience and back up.

What about voice quality?

tIPicall’s network has Quality of Service (QOS) which provides the same quality of voice as a normal telephone line. Providing that your router and data network can support QOS, you won’t notice any difference in voice quality.

So, why isn’t everyone using SIP trunking?

SIP trunking is still relatively new technology but as good news travels fast, more and more businesses are moving over to SIP. In the long run, all voice services will run over an IP backbone.
