CET’s international voice gateways at the Hameln teleport and at Telehouse in London enable carriers, corporates, governmental agencies and other organisations to use VoIP as means of carrying voice traffic between the various locations on their networks. VoIP is becoming the technology of choice for voice communications whether it is for PSTN or GSM links into or out of emerging market countries, where traditional voice links are expensive or outmoded. VoIP is also widely used for the international parts of dedicated links between nodes on the networks of multi-national organisations.

The CET softswitches at Hameln and Telehouse convert the incoming PSTN or GSM protocols into IP traffic for transmission over the satellite link. At its destination it is converted back into the protocol the local PSTN or GSM operator is using for local delivery. Where organisations originate their voice traffic from remote locations in IP, CET’s voice gateways convert it to the local PSTN/GSM protocol for onward transmission and vice-versa.

CET’s connections into the Deutsche Telekom fibre network in Germany and to the international fibre network in London provide its customers with the widest, most cost-effective routing options for their international voice traffic.
