When Attempt to Dial an extestion on same call manager, it dials successfully but when try to press cancel call it displayed 

"xml error [4] parse error"

A java class creates XML to Push on Phone

"<?xml version="1.0" encoding="utf-8"?><CiscoIPPhoneResponse><ResponseItem URL="Dial:8910" Data="Success" Status="0" /></CiscoIPPhoneResponse>"

and it is only shows xml error on this phone only, other phone versions are working just fine.

For Call manager:

Cisco Unified Communications Manager [System version: 10.5.1.10000-7]

Please Advise.
