What are SIP trunks?
SIP trunks (or VoIP trunks) enable users to utilise a single internet connection for making and receiving multiple concurrent telephone calls. SIP trunking provides you with added flexibility, improves business continuity and offers substantial cost-savings over traditional telephony services.
By utilising SIP 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.
How it works
SIP (Session Initiation Protocol) is a signalling communications protocol used to create, manage and terminate multimedia communication sessions in an IP-based network. A session could be a simple two-way telephone call, or it could be a collaborative multi-media conference session. Once the session is set up, further protocols/software (e.g. codecs) are required to convert the audio stream over SIP.
SIP trunking provides virtual telephone lines over a high speed IP network, connecting to an IP PBX. In Telappliant’s case, this is a VoIPOffice (i.e. a hosted PBX). Thus, all the customer needs is a fast internet connection, and this in turn, dictates the number of concurrent calls to be made.

Urfan Azad from Gold Travel says...
"Telappliant has been brilliant. Our first experience of a VoIP provider wasn't particularly good, but since we've switched to Telappliant we haven't looked back. We love the features and flexibility of the system, and the support we receive from our account manager is excellent."
Irfan Dadabhai from Conrad Electronics says...
"We discovered Telappliant following a recommendation from a client. This is our first experience of VoIP telephony and we are extremely happy. VoIPOffice is very easy to use and provides us with the information we needed to ensure each agent in our UK Customer Contact Centre is managed effectively. "
Henry Ayres from AngloINFO says...
"Telappliant were more than happy to meet our changing needs with a flexible and accommodating package. Their VoIPOffice business telephone system is extremely cost-effective, scalable and reliable, and their ongoing support is invaluable "
Ben Sargeant from Douglas Stafford says...
"While we use most of the VoIPOffice phone system's functionality, we've found the online call monitoring and call recording particularly valuable for improving customer service. All our calls are through VoIPOffice and the system has proved to be very robust and reliable."
Gupi Wasan from E-Services Group says...
"Telappliant brought together our three separate analogue phone systems into one low cost, high performance solution. I would most definitely recommend Telappliant to other businesses, especially call centres and those looking to unify their telecommunications."
Trevor Tsang from Reassured says...
"Over the years, VoIPOffice has grown with the business and proved to be reliable and to significantly reduce our overheads. Telappliant is always happy to respond to our unique demands and I highly recommend VoIPOffice Hosted for Call Centres to other businesses."
