The IP-voice technology has finally enabled reasonable quality of the voice service, and can be effectively integrated with the ordinary Internet traffic. The Voice traffic in our VoIP solution is based on IP and will be terminated through Vizada international Exchange in Oslo, Norway, therefore we can guarantee the highest quality of our voice service.

The development within the IP-voice area has been very fruitful and expanding. There are a lot of commercial products released, which enables the integration of IP-voice into an existing IP data-stream.

Vizada has for a long time experimented and tested IP-voice CISCO routers together with VSAT technology with very good results and experience. These routers offer primary and basic rate ISDN as well as analogue interfaces for connection of PBXs or stand alone phones.

Nashita’s VoIP billing procedure

Customers at each site will be billed on monthly basis for their VoIP charges.
