Hi, I am using the presence_xml module to provide presence across multiple clients. X-Lite, Bria works well however Snom phones produce the following error: ------------- ERROR ----------------namespace error : Namespace prefix hs on detected-state is not defined hs:detected-stateLunch</hs:detected-state> ^namespace error : Namespace prefix hs on device is not definedtact priority="0.000">sip:--- ADDRESS ----</contact> <hs:device ^namespace error : Namespace prefix hs on caption is not defined hs:captionsnom370</hs:caption> ^namespace error : Namespace prefix hs on detected-state is not defined hs:detected-stateBusy</hs:detected-state> ^namespace error : Namespace prefix hs on device is not definedtact priority="0.000">sip:--- ADDRESS ----</contact> <hs:device ^namespace error : Namespace prefix hs on caption is not defined hs:captionsnom370</hs:caption> ^namespace error : Namespace prefix hs on detected-state is not defined hs:detected-stateLunch</hs:detected-state> ^namespace error : Namespace prefix hs on device is not definedtact priority="0.000">sip:--- ADDRESS ----</contact> <hs:device ^namespace error : Namespace prefix hs on caption is not defined hs:captionsnom370</hs:caption> ^------------- END ERROR ----------------It looks like a validation issue with the XML, is there anyway you can switch off validation or update the DTD?
