There is a 1yr manufacturers warranty, I think there's typically about 2 or 3 month leeway added in, I would try to RMA anything you can. Since ours aren't covered under smartnet either, I have to call or use the chat from the Cisco website to try and RMA. If you didn't already know, the manufacture date is down in the corner near the battery contacts.
Sorry, but this is no solution in my case.
We are using only original Cases from Cisco and still we have about 70-80 defective mics on 8821s. At the moment we are using about 550 of those 8821s. Those are rugged phones, there´s an EX version and a "third party supplier phone case" should cause the phone to fail?
In general we have replaced around 200 of the phones, makes around 750 phones with 200 defects... one out of four phones is not working anymore.
A real solution would be to sell replacement microphones. If you have some, let me know, we´re willing to pay for spare parts.
We had phones destroyed by colleagues (i.e. broken displays) which are NOT counting to the 200 defects, we removed the mics and fixed other 8821 which aren´t within warranty anymore... so this would be a thing to make us really happy.
Exactly the same problem... We have roughtly 120 Cisco 8821 now in production (and still 600 Cisco 7925)... We intended to slowly switch all our park to 8821 models...
But today after 2 years deploying progressively 8821, I have more than 30% coming back with such mic problems...
As many here, I've done everything to try to resolve this issue (reset to factory, firmware updates, etc...) but it really seems to be a hardware problem.
It's just unbelieveble that Cisco don't do anything for that !! Our account manager even don't seems to be aware of that problem !
The problem is that we're blocked, 7925 are not orderable no more and 8821 are really not reliable... What can we do ?! Is there a Cisco roadmap for a new wireless phone model ?!
We´re not buying Cisco anymore.
Cisco isn´t even customer-orientated as much to act as they should. There is a failure on that product, it was never working well, it´s dying like a fly and they should refund money and stop that phone.
Alternatives are i.e. the Ascom I62.
There are even Cisco gold partners who aren´t selling this thing anymore.
And the best alternative is DECT over IP. Just google for it... we had ~40 antennas in our plant and could also reach the parking lot and signal was available on the roof of the buildings. Today ~230 antennas, no signal on parking lot, building roofs, even the fences are not reachable and we have still some areas with weak signals...
Just. go. DECT.
I hear you....I have been sending all the bad phones back to Cisco for last few months. No one knows what is going on with mic situation!!! One time I heard that Cisco has been looking for different manufacturer for mic...not sure how true that is?
Are these ASCOM phones would work with same infrastructure as Cisco phones? What is the average cost of each phone?
We're replacing a very reliable (but EOL) Spectralink 900 MHz system with 8821's and I'm enemy #1 here at work now. The handsets were fairly basic - and we replaced a fair number of them due to wear, tear and abuse - but the system simply worked well in an industrial environment. Even the guy who helped put it in (who's now selling industrial headsets, mics, etc... for radios) said we'd regret it. He's right! Good times. But need to move forward as we can't rely on grey-market / refurb equipment forever either.
