Get more out of your Communications
An increasing number of corporations consider a switch to SIP, not only for its greater flexibility and immediate costs savings, but it also helps optimise their network investment
SIP (Session Initiation Protocol) is an open standard technology that allows you to make calls over an IP connection, rather than a traditional phone network.
Thanks to the SIP protocol solutions like Voice and Video over IP have conquered not only a place in the private segment, but it also forms the cornerstone for communication solutions for corporations.
As one of the first providers Dia Telecom came with solutions that use open standards and comply with the requirements of the market. In the development of our SIP based products our years of experience in the field of voice, video and data has been decisive.
Our SIP trunk brings you the benefits of Voice over IP (VoIP) while retaining your telephony exchange equipment at your location.
