    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Cisco Wavelink (Avalanche) Bug:CSCtb45669 Code 1.3(3)

We are deploying thosands of Cisco 7925 handsets with Wavelink. After extensive testing I discovered that I could not get the phone to reboot after a profile push. I reached out to Wesley Terry (Cisco's Escalation Team) and BAM! He delivers for me ... Thanks Wesley !

792x is not reprovisioning after receiving Wavelink package

Symptom: 792x is not reprovisioning after receiving Wavelink package.
If updating profile 1 or switching from profile 2, there is no provisioning trigger occurring, but the network profile config is updated.


The phone stays connected with the previous network profile information even if not existing in the network profiles.

Condition: Pushing a package to the 792x via Wavelink.

Workaround: Power cycle the phone

 

This is resolved in code 1.3(4)
