ShoreTel, a provider of IP phone systems with integrated unified communications (UC), has released the new version of its UC software ShoreTel 11.

The company said that its new release features client for the iPhone and a distributed database, which help large businesses simplify system management, improve reliability, and lower communications costs.

The ShoreTel Communicator client is now available for the Web and for the iPhone, allowing users to manage communications from Macintosh computers and iPhones, along with BlackBerry and other popular devices.

ShoreTel said that it has enhanced the distributed architecture of its UC software with distributed database capabilities. ShoreTel 11 offers extended legacy PBX integration capabilities with expanded QSIG support, which makes it easier for customers to migrate to all IP-based UC capabilities over time.

Kevin Gavin, vice president of marketing at ShoreTel, said: "With this latest system software release, ShoreTel takes another giant leap forward in delivering on the promise of unified communications for organisations of every size.

"ShoreTel 11’s enhanced distributed architecture, new iPhone client, and extended support for legacy PBX systems all drive down deployment costs and TCO, while increasing reliability and flexibility."
