Greetings, can i ask if anyone has had a similar to me when deploying the UC520 (All Versions 8 - 64 User)
I have noticed that when running IOS v12.4(20)T2 (CME Version 7.0(0)) in combination with 524SG handsets and following a cold reboot of the appliance the 524SG handsets fail to re-register and require manually power off then on again either by pulling the ethernet cable out the back of the phone or shutting down the appropriate switchport and enabling it once again.
Actual performance of the handset isnt impaired once registered however i am interested to know if anyone has experienced a similar issue, i have tested this on the the following models:
We just announced the availability of a new CCA and new software packs. The 521-524 load in this packs is 8.1.16b. Please try to upgrade to that version and let us know if you still see issues.
