Aruba Adds VoWLAN Features, Certifications

By Glenn Fleishman

Aruba will interoperate with SpectraLink, Vocera, Avaya; adds new packet-based VoWLAN spec: Two big announcements on voice from the company that Microsoft picked to replace aging Wi-Fi equipment across their Redmond campuses and worldwide. Aruba says they are certified by SpectraLink, a veteran enterprise VoIP and VoWLAN firm; validated by Vocera, the Wi-Fi badge/intercom maker beloved by nurses and supply-chain logistics managers; and is part of the Avaya developer program.

Simultaneously, they’ve announced Voice Flow Classification (VFC), which is a packet-inspection and prioritization protocol which allows handsets, firewalls, and access points to be coordinated to avoid speech clipping on calls and overloading calls on individual APs. The technology provides prioritization at the firewall level, and monitors off-hook calls throughout a switched WLAN environment to push calls to APs that have capacity. It suppresses handset scanning when that would interfere with a call, too.

There’s an interesting small option noted in this protocol, too, which is that devices that hop on a network to access voice functions can’t pass regular data. This is intended to prevent security holes for enterprises using handsets that don’t have robust authentication.

VFC is part of their 2.5 platform update, which is free to existing users and available this month.
