It certainly seems that the Aastra 6739i is the new king-of-the-hill with respect to feature-laden enterprise class SIP desk phones. Amongst it’s myriad features you will find included the ability to use a Bluetooth headset .
For the past nine months I’ve used the Savi Go Bluetooth headset around the office. In that case I’m using the headset with a soft phone since the Savi Go is provided with a class 1 Bluetooth USB dongle. The Savi Go is kinda unique because it supports wideband audio over Bluetooth.
The Class 1 Bluetooth radio permits me to wander up to 100 feet from the dongle while sustaining a call. It’s a great cordless mobility solution for a small office.
This raises an obvious question; does the Aastra 6739i support wideband audio over Bluetooth? I put the question out to a couple of people I know who have used the 6738i, but neither of them have yet used the phone with a Bluetooth headset so the mystery remained.
I then put the question to Aastra tech support. Earlier today they responded with a PDF document that gives guidance for using both wired and wireless headsets with the 6739i. Here’s that document:
Looking into that document I find the following wireless headset are recommended:
While I am not intimate with every Bluetooth headset on that list, I am generally aware of those few headsets are truly wideband capable. These tend to be headsets that target use with corporate Unified Communications applications like Microsoft OCS.
My guess is that none of those recommended handle wideband audio.
This doesn’t mean that the phone itself is not capable of wideband audio over the BT link. Perhaps Aastra will make some kind of statement about this when asked.
It’s also very possible that someone who owns a 6739i might try to pair it with something like a Plantronics Savi Go (right) or Plantronics Voyager Pro UC. Both of those headsets are known to be wideband capable.
