Cisco, Nokia push Wi-Fi VOIP/cellular convergence

Cisco expands support of Nokia smart phones on its enterprise VoIP and WLAN infrastructure

Cisco and Nokia have announced new dual-mode smart phones that can operate on a Cisco enterprise VoIP infrastructure and a public GSM network.

The dual-mode Nokia E61i and E65 smart phones contain both 802.11g and GSM radios, as well as software that allows the devices to sense which network signal is strongest and place calls accordingly. The Nokia handsets also have software allowing them to operate as a corporate phone extension off of a Cisco CallManager IP PBX and messaging infrastructure. The new phones were announced at 3GSM World Congress in Barcelona this week.

Cisco kicked off its partnership with Nokia last year, when it announced compatibility between Cisco's Unified CallManager 5.0 system and Nokia E60, E61 and E70 smart phones. This interoperability allows a Nokia phone to receive VoIP calls switched via a Cisco IP PBX, the same as a wired desktop IP phone, or a Cisco 802.11-based handset.

The race to link mobile phones with corporate VoIP systems has heated up recently among IP PBX makers. Avaya and Cisco both recently acquired companies that allow mobile phones and smart phones to access corporate VoIP networks and messaging applications. Avaya bet $US15 million on Traverse Networks , a maker of fixed-mobile convergence software for mobile phones, in November. The month before, Cisco bought Orative, which makes similar software, for $US31 million.

While Nortel has remained quite on the FMC front, industry observers say a tighter connection between Nortel's corporate VoIP technology and Microsoft's smart phone/handheld software is a reasonable expectation, given the two companies' Innovative Technology Alliance, a four-year product development, sales and support partnership.

Enterprises are interested in melding users' mobile phones with corporate telephony for several reasons. Some say an enterprise with a large base of mobile phone users can cut costs by allowing employees to make calls more cheaply over a corporate VoIP-enabled Wi-Fi network, or at Wi-Fi hot spots or public wireless networks.

Tying mobile phones closely to a corporate VoIP network also can provide the convenience of a single phone number for employees. In addition, administrators could gain more centralised control over corporate data - such as emails, contact databases and voicemails - which normally spread out across individual workers' phones.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
