The BlackBerry site has just posted a new support document entitled Deploying the BlackBerry 7270 Wireless Handheld from Research In Motion with a Meru Networks WLAN.
The BlackBerry 7270 uses UDP-based SIP for call setup. As a result the Meru Networks WLAN is able to execute automatic detection of the codec and IP/port in order to reserve and admit new calls.
Meru says the key benefits in using their system include:
Quality of Service is maintained for voice calls when there is a converged network of mixed data and voice.
Seamless handoff between access points resulting in excellent voice quality and no audio drop-outs during roaming;
With the optional Voice Service Module (VSM) you can control call admission in order to limit the load of calls on the network or to preserve quality when users attempt to place more calls than the RF will support.
