Time for wire captures I’d say.

<div>Compare headers with and without AnyConnect. Do the markings change? Is there excessive broadcast traffic hitting the NIC when using AnyConnect? ... etc.

<div>TAC will want that anyway so getting traces setup won’t be a wasted effort. Outside of that, you’re just going to be stabbing in the dark hoping to hit something :).</div>

<p class="MsoNormal"><span style="color:#1F497D">Thanks for responding. Running Cisco Jabber 11.8.3. We are only using AnyConnect NAM as a supplicant for 802.1x/ ISE. Not using for VPN at all. This is happening internally on site connected to our Cisco wireless
environment that uses 3602/3702 APs and 5508 WLCs. I know it is crazy but it seems directly related to us installing AnyConnect.

<p class="MsoNormal">We have installed AnyConnect 4.5 and have started to have issues with Jabber calls using wireless. Every minute outbound voice becomes garbled for several seconds Running a continuous ping from a PC to the wireless default gateway we
jump from 2ms to 160+ms every minute that corresponds to the garbed voice. Opening a TAC case but curious if anyone else has seen this behavior. This does not occur on a device without AnyConnect and if you uninstall the software everything works fine. This
also does occur when connected wired using AnyConnect.<o:p></o:p></p>
