In providing telephone numbers with connection through IP and SIP technologies, Mastertel assists the client in creating a reliable and ‘unauthorized-access-protected’ connection channel with the potential to build internal and external telephony systems in addition to a well developed set of accompanying telecommunications services.
We recommend connection through IP and SIP as a more modern way of organizing one’s telephone system in large companies. This type of connection means that voice and data transmission is performed through the same channels. Depending on the client’s needs, the most important type of traffic is given priority. We connect clients through digital data channels or directly through the Internet with security protection for all information transmitted.
Services may be provided within the framework of a virtual private network or through the Internet with its high level of security for transmitted information. Should it be necessary to link up to Mastertel's network, a private virtual network may be set up using fiber-optic lines.
