     Hi All.

We have following setup--

User Phone=====>Wifi Device (non sip aware)========> WLC========>SIP Proxy

We found when User A and User B calling each other (both under above setup)  call got connected but when User 1 sending SIP sessio  refresh message  UPDATE we found 3-4 Update message modify by Cisco WLC and adding fo charcater before Update message.

fo<UPDATE sip:211222@user.com

Not sure why WLC adding fo update character is this bug in OS as fo character added in 3-4 session refresh by WLC.

PLease help me if any one come across this porblem/

Hi Bsant I dont think it will solve my problem,as WLC adding fo parameter before UPDATe message randomly. in given link no configuration to check ori aviod that "fo" parameter.

PLease sugggest is it bug at OS level.
