Solutions for smooth conversion to VoIP

Voice migration is one of the key issues for every network provider. The goal is for previous TDM voice data to be converted immediately or gradually to VoIP.

DZS solutions have both a V5.x interface and a VoIP media gateway function, based on H.248/MEGACO and SIP. So you can continue to offer legacy telephone services (POTS/ISDN), but also convert your network to a standard VoIP architecture already.

IP-MSAN MileGate

MileGate combines carrier-grade broadband access, telephony and data interfaces in one single Next-Generation Access Platform that is excellent for the FTTx architecture. As a result, network operators can carry on supporting legacy telephony and broadband services, at the same time as migrating to the NGN (Next Generation Network) and providing top-quality Triple Play and broadband business services as well. With its V5.2 interface, MileGate allows you to offer modern DSL services and at the same time make use of existing investments in the exchanges. By simply downloading software, you can swap your exchanges for a soft switch, without having to reconfigure or switch over your subscriber line.
