This iPhone doesn't use the cellular network, instead it allows users to connect to their SIP and VoIP networks to make calls wirelessly.

The WIP 310 is the third phone available under Cisco's iPhone brand. As some may remember, Cisco sued Apple in January 2007 over use of the name, but reached a licensing agreement only a month later.

Cisco says the phone integrates voice calls with Internet connectivity to provide customers with access to multimedia content.

"The WIP310 is designed to mesh wireless connectivity with IP-telephony into a sleek form factor offering service providers a compelling and cost effective new solution ideal for consumers and small business subscribers," voice product chief Sherman Scholten said.

Features of the phone include a 1.8-inch TFT LCD, hands-free phone jack, mini USB ports, polyphonic ringtones, and speaker phone capability. The phone is also firmware upgradable.

Service providers should not have a problem setting up phones with standards-compliant SIP networks or gateways. Wizards are provided with the phone to make setup easy for end-users, Cisco said.

Availability has been set for the third quarter at a retail price of $199.99.
