Teles Class4 Softswitch

Like the Internet, voice communications networks are made up of a number of individual networks run by different operators that differ in terms of their architecture as well as their signaling and transmission technologies. Network operators need to connect their own network to the telephone networks of other operators to provide their customers with connectivity worldwide. Softswitches from TELES allow heterogeneous networks around the globe to communicate with one another and exchange signals with no disruptions.  

The transition to IP telephony and new IP applications is advancing very quickly on the consumer end, in the core networks of operators and in the area of interconnectivity. In this manner, the geographic coverage and earnings potential of network interconnections is growing – accompanied by simultaneously shrinking costs for termination in the fixed network. 

For the transition from conventional line-switched networks to IP networks, TELES offers network operators integrated, high-availability and scalable Media Gateways. 

Whether they are SIP, SIP-I/-T or classic SS7 ANSI and ITU-T variants with a wide range of national variants supported – the TELES Softswitch addresses all relevant signalling protocols and thus ensures seamless connections and communications in all directions.

The integrated STP functionality enables the connection with other SS7 or mobile communication networks. SS7 messages can be routed based on their MTP3 routing label.  

Furthermore via an efficient Global Title Translation (GTT), the targeted routing of SCCP messages – based on a Global Title (GT), Subsystem Number (SSN) and point code – is possible. 

The extremely flexible routing control and steering permits the recognition and manipulation of a wide range of SS7 and SIP message signalling parameters. The integration in external OSS/BSS systems occurs via open interfaces, among others for steering the routing and for the billing. In this way, traffic flows and profit maximisation can be optimally managed. 

The support of IN environments for number portability (NP) and an expanded IN-based call control are also aspects which favour utilising the TELES Softswitch for the migration of existing networks. ENUM and an integrated NP database are also available as additional integration options.
