[cisco-voip] AnyConnect Wireless and Jabber Voice

[Ryan Huff]

Sounds like jitter .... usually QoS related.

Spitballing here cause I don’t know your topology but it sounds like the traffic is getting marked best effort when traversing the VPN connection.

If you can illustrate the Jabber client’s connection path (and type of Jabber client), I might be able to help a little more.

Is this an on-prem Jabber install? Always a good idea to run through this guide as well for on-perm installs: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/11_5/CJAB_BK_D00D8CBD_00_deployment-installation-guide-cisco-jabber115/CJAB_BK_D00D8CBD_00_deployment-installation-guide-cisco-jabber115_chapter_010001.html

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.
