Motorola has expanded its family of voice-enabled cable modems with the introduction of its SIP-enabled SBV5100 series. 
Motorola expects many cable operators will adopt SIP-based devices for their networks as a migration path toward PacketCable 2.0. SIP, along with Quality of Service (QoS) based on PacketCable Multimedia (PCMM), provides a foundation for the delivery of advanced services, including fixed-mobile convergence (FMC) — allowing consumers to “hand off” a cellular call to a Wi-Fi network and landline phone, rich multimedia communications, such as interactive video sessions, secure signaling and encryption, and flexible Network Address Translation (NAT) and firewall traversal technologies like Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (STUN).
The Motorola SBV5100 series, which is expected to be available by the end of 2006, supports full-featured primary VoIP telephone service for up to two telephone lines that are terminated in two RJ-11 connectors. In addition, its integrated cable modem connects to a computer through either a 10/100Base-T Ethernet or a USB data port.
