Sprint announced Wednesday an integrated and enhanced VoIP services portfolio for cable companies. The new set of services is likely to put additional pressure on telco legacy landline offerings.

Sprint's new services include Caller ID to the TV and PC, and new voicemail features, including a SMS text alert sent to a mobile phone and voicemail to email. Caller ID to TV and PC can be customized by adding pictures, nicknames, fonts and colors. The SMS text alert for home voicemail includes the telephone number of the calling party.

Sprint provides wholesale cable VoIP services to 14 leading cable companies and supports more than 4.5 million cable VoIP/digital phone subscribers - covering more than 31 million cable households-passed.  

As cable players move into wireless services, Sprint and its Clearwire spinoff and VoIP all have key roles to play. For cable players organically building their own wireless capabilities, such as Cox, Sprint stands ready to provide CDMA roaming (and this reporter strongly suspects LTE roaming down the road). Clearwire is already testing mobile WiMax phones. VoIP will be the "glue" to handle handoffs between cable and WiMax calls.
