摘要:
As competition from wireless and cable providers heats up, wireline service providers may respond by deploying a VoIP core network to reduce overall network costs and offering advanced IP-based services to retain profitable voice subscribers. SIP (Session Initiation Protocol) is capable of powering both of these responses and as such, will be the foundation of profitable PSTN evolution.
