AP 1121 minimum IOS for cisco 7921 initial voice delay in calls problem

Unanswered Question
Jun 7th, 2010


I have AP's 1121  ( autonumous mode)  with IOS (12.3.8JA2)  but i saw in 7921 deployment guide that minimum IOS required is 12.3.8JEA2. or later

But i have seen in download area says that 12.3.8JEA3 is ( LD) so what IOS version should i upgrade to?

I want to try to upgrade AP's because sometimes in begin of incoming calls  i have a delay of 3 seconds in audio (only happens with 7921 phones ). I have already  tested with several firmwares of 7921 phones and problem remains.

Any suggestions?


Best Regards


I have this problem too.

The reason you need to run the 12.3(8)JEA or later version is because of the wireless QoS.  The QoS features such as CAC and TSPEC weren't added to the AP's until those versions.
