W56P answering randomly

[DavidDDD]

We have 6 W56P handsets on 2 base stations (3 per base station).
Recently one of them, not always the same one, will auto answer a call on speakerphone. "Auto Answer" is turned off on all the handsets.

The 6 W56P phones, along with 7 desk phones are in the same ring group (6400). In this example one of our handsets on ext 6020 'answered' the call on its own.

Note the duration for ringing desk phones is 2 seconds, except the W56P phones. Ext 6010 is a W56P, didnt answer, but shows 9 seconds duration.

I deployed the firmware to both base stations and all 6 DECT phones on Saturday, and added them back to the ring group. We have had no recurrences of the handsets answering the phones unexpectedly since then. Normally we would have this happen several times a day. So I think our issue is resolved. I'll report back in a few weeks to confirm the fix has indeed resolved the problem.

Thanks for your help.

OK, thank you for your reply.

I have the same issue.

W52P/W56P base randomly answering calls.

The previous firmware link does not work.

Will this firmware fix it:

Base for W52P&W56P-25.81.0.60

Please let me know.

Thanks!
