Restrictions for Configuring Reanchoring of Roaming Voice Clients

  • The ongoing data session might be affected due to disassociation and then reassociation.
  • This feature is supported for TSPEC-based calls and non-TSPEC SIP-based calls only when you enable the admission control.
  • This feature is not recommended for use on Cisco 792x phones.

Information About Reanchoring of Roaming Voice Clients

You can allow voice clients to get anchored on the best suited and nearest available controller, which is useful when intercontroller roaming occurs. By using this feature, you can avoid the use of tunnels to carry traffic between the foreign controller and the anchor controller and remove unnecessary traffic from the network.

The ongoing call during roaming is not affected and can continue without any problem. The traffic passes through proper tunnels that are established between the foreign controller and the anchor controller. Disassociation occurs only after the call ends, and then the client then gets reassociated to a new controller.


Note


You can reanchor roaming of voice clients for each WLAN.
