The Agito Networks RoamAnywhere Mobility solution includes top-notch Wi-Fi fingerprinting technology, enabling mobile phone users to easily move about while saving businesses money on mobile minutes. The new Agito RoamAnywhere technology also offers high availability and additional security features.
The Agito Networks RoamAnywhere Mobility solution does an excellent job of
wedding a user's mobile phone to the corporate PBX, allowing users to
seamlessly place and receive calls using their business extensions and to
leverage the corporate directory no matter where they might be or what network
they are connected to.
With its excellent Wi-Fi fingerprinting technology, Agito's fixed mobile
convergence solution efficiently handles the transitions from WLAN to cellular
resources, allowing a business to save money on mobile minutes without
requiring the user to do anything special. With Version 2.0 of the
RoamAnywhere solution, which was released in October, Agito added
mission-critical high availability as an option and layers of additional
security features so remote users can leverage Wi-Fi network connections as
Agito's RoamAnywhere solution consists of two parts: the RoamAnywhere client,
which can be installed on an assortment of smart phones running Windows Mobile
6 (both Standard and Professional) or the Nokia E- and N-Series devices, running
Symbian; and the RoamAnywhere Mobility Router, which sits in the corporate data
center and works in concert with the PBX.
Agito offers two versions of the Mobility Router, with options for high
availability on the larger solution. The smaller of the two, the
RoamAnywhere 2000, supports up to 100 users for a list price of $24,195. The
bigger box, the RoamAnywhere 4000, supports up to 1,000 users, though I priced
it out for 500 users, which would cost $109,995.
The RoamAnywhere 4000 can also be paired with a second appliance for high
availability. The second unit comes with a bit of a discount when bought
together for redundancy-the pair of RoamAnywhere 4000s costs $186,192 when
licensed for 500 users.
The devices operate in an active/passive relationship, where the second one
will take over call routing duties if the first fails. In tests I found
active calls would continue uninterrupted if I pulled the plug from the primary
unit (although this is not surprising given the system's architecture).
Agito maintains both a trunk-side and a line-side relationship with the
PBX. In most cases, Agito-enabled phones conduct signaling duties in
conjunction with the Mobility Router, while the call payload goes directly to
the party on the other end, if end-to-end SIP (Session Initiation Protocol), or
to the PBX for calls with the PSTN (Public Switched Telephone Network). Only
when the smart phone is connected to a foreign Wi-Fi network will the call
payload traverse touch the Mobility Router, requiring the trunk-side
With the phones actively communicating with the PBX, a line-side
relationship has the potential to allow a richer subset of the PBX features to
an FMC client. However, this type of
integration also requires much work from Agito to ensure that supported devices
continue to work when a PBX is patched or upgraded, so customers need to talk
with Agito before performing upgrades on the PBX itself.
Agito is prequalified to work with Asterisk, Avaya, Cisco Systems, Microsoft
and Nortel IP PBXs, but I found Avaya and Cisco were best supported, as I could
bulk-configure extensions on the PBX from Agito's Web-based configuration
pages. Testing Agito in conjunction with a Cisco Call Manager, I found
that depending on the configuration, the administrator will need to make
several changes to PBX configuration-for instance, to twin the mobile phone with
a desk phone, allowing both to ring simultaneously.
Agito is also prequalified to work with several enterprise-grade wireless
network solutions, including solutions from Cisco, Aruba Networks, Aerohive
Networks, Meru Networks, and Belden's Trapeze Networks. However, the
Mobility Router should work with most wireless networking solutions (802.11g or
better), although Agito recommends the network support the WMM spec and 802.11i

pre-shared key. Agito does offer further integrations with both Cisco and
Aruba WLAN controllers to leverage those companies' adaptive radio management
