“Mobile VoIP is no longer just a cheap telephone call,” notes John Blau, research analyst with Unstrung Insider and author of the report. “The big advantage of VoIP is its ability to integrate with other systems and stimulate further adoption.”

Mobile VoIP represents a promising and natural step forward in the continued evolution of mobile networks, and operators will need to come to grips with these changes, according to Blau. “Although many mobile operators continue to block VoIP calls to protect their voice revenues, that strategy will not be sustainable,” he said. “Sooner or later, mobile operators will be forced to deploy their own VoIP services, since next-generation networks such as Long Term Evolution (LTE) and WiMax are all-IP and do not support circuit voice.”

Key findings of Mobile VoIP: A Disruptive Service Goes Mainstream include:

– Many mobile VoIP players are broadening into other applications, integrating with other systems, and stimulating further adoption. — New services such as voice-enhanced IM, voice mashups, and voice plugins are being used to build communities. — Operator resistance to mobile VoIP is gradually softening worldwide, as major incumbents such as T-Mobile drop their bans. — New Flash technology enabling peer-to-peer voice capability without requiring plugins or soft clients could be a game-changer. — Venture capitalists remain interested in disruptive mobile VoIP technology, which they view as still in its early days of development.

– Security is an ever-present issue in wireless markets, but the WPA2 standard provides robust security.
