SPA525G2 Plantronics Voyager UC V2 Bluetooth Failure


Software Version: 7.4.8

Bluetooth Firmware Version: 0.00.32a

When attempting to pair a Plantronics Voyager PRO UC B230 I receive the error, "Pairing Failed"

It worked twice, but I had to reset the phone and I could never get it to pair again. It was nice when it worked

I have tried through the phone's gui and the phones web page. I have power cycled and opened Cisco STAC support requests. We tried to downgrade the phoen's firmware, and upgrade the Plantronic's firmware - no help.

I am able to pair the Plantronics headset with my iphone, and my iphone with my SPA525G2.

Cisco SPA525G2 BT.log (Diagnostic log) follows;

SPA525G2 Plantronics Voyager UC V2 Bluetooth Failure

Hi Brook;

Quick question, which BT mode you have the SPA525G set to? (phone, headset, both)...try setting it to headset.

Please note the phone supports just one BT device at a time, i.e. headset or phone, not both.

The Voyager UC V2 is Plantronics newest, best selling hands-free headset.

The Cisco SPA525G2 is Cisco's best sellign VOIP phone.

The Plantronics headset will not pair with any Cisco SPA525G2 with the 7.4.8 firmware.

The only compatable Cisco SPA525G2 firmware we have discovered is 7.4.7.

We would be greatful if you could fix this in the next update.

I believe I saw that there is a 7.4.9 firmware out for the SPA525G/G2 that also includes a Bluetooth firmware update as well.  I cannot speak to what impact that will have, just pointing it out.

Thanks for the heads up.

I just saw the 7.4.9-bt update after I posted and have applied the update via the phone's GUI.

The 7.4.9-bt firmware does not resolve the issue. The same pairing issues remain.

Now I am stuck with Bluetooth formware Ver 0.34 that came with Phone firmware Ver 7.4.9 and I can roll the phoen firmware back, but not the bluetooth. Ugh.

Updated to firmware 7.4.9C and still cannot pair.

Cisco, can you please fix this?

Im going to try to downgrade to an earlier Bluetooth version on the SPA525G2 if it will allow it - back to a Bluetooth version that works.
