Florian Hanig commented on ASTERISK-13145:
------------------------------------------

I’ve now found the bug / problem with the 8821 Cisco WLAN Phone.
It’s a bug of the Cisco Phone itself.

I’ve now spend more than 30 hours for analyse and testing with this phone.

It seems it is the following bug listed on Cisco:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvc03460/?referring_site=bugquickviewredir

I also see witth „sip show channelstats“, that the phone has problems with Jitter…

So the workaround from Cisco is, to switch the phone WLAN Scanning Mode to Single AP Mode.
(<scanningMode>1</scanningMode>) in sep.xml

With that mode, all Problems goes away, but now Roaming with my Cisco WLC are not possible.

I’ve opend a ticket on cisco to solve this bug.
I think cisco will publish new firmware for the 8821 phone, in time.
