Network migration: Carrier

With the TELES Softswitch solution, all of the class 4 scenarios are mapped on a platform:

  • International long distance and International Gateway Solutions on TDM and NGN/VoIP technology
  • Wholesale Solutions on a TDM and NGN/VoIP basis, with the support of Wholesale Trading Platforms
  • Carrier Interconnects on a TDM (SS7) basis, with TELES MGC and Media Gateways
  • Carrier interconnects on an NGN/SIP basis, with TELES Interconnect SBC (NNI-SBC)
  • Replacement of existing systems (e.g. Cisco PGW) while continuing to use the existing Media Gateways


  • NGN/VoIP and classic TDM (SS7) peering running on one platform
  • Central routing for both worlds
  • Media and Signalling Gateway support – regardless of the manufacturer
  • Investment security thanks to the dual usage support for media gateways (TDM resources become transcoding resources in VoIP peering)
  • Carrier class scalability and availability
  • IMS-conform architecture (BGCF, MGCF, SGW, MGF, T-MGF, IBCF, I-BGF)
  • NFV software solution on COTS servers
  • Significant OPEX savings compared to legacy switching platforms (in terms of the power, space, support, etc.)
  • More than 25 years of international experience setting up and migrating voice networks
