Cisco WLC adding fo parameter in SIP UPDATE

[amitsalunkhe21]

     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/
