SIP Trunks

What is SIP trunking?

VoIP (or SIP) trunks enable enterprises to utilise a single Internet connection for making and receiving multiple concurrent telephone calls. VoIP trunking provides your organisation with added flexibility, improves business continuity and offers substantial cost savings over traditional telephony services. By utilising VoIP trunks within a converged voice and data network, you can dynamically allocate bandwidth to other needs such as email and web traffic as and when you need it.


With savings of over 60% on existing line rental charges and with advanced features such as Dynamic Line Allocation, Flip Connect is ideal in a mixture of business environments. Whether you are looking for line replacement, additional capacity or a disaster recovery implementation then Flip Connect is ideal for you.
