Push IPPhone Service to Phone

I am trying to determine if there is a way to remotely push an IPPhone Service URL to a phone, so that I don't have to expose another option to my user community.  The service I am attempting to execute is IPMA phone services URL:

http://callmanager.example.com:8080/ma/servlet/MAService?cmd=doPhoneService&Name=#DEVICENAME#

If I push the above URL, it returns '<CiscoIPPhoneError Number="1"></CiscoIPPhoneError>'.

Before I continue down the road of troubleshooting the response error, is it even possible to issue a phone service request via CiscoIPPhoneExecute?

You should be able to push any URL to the phone.

A few things to check:

- The HTTP POST includes 'Content-type' header of 'text/xml'

- The actual target URL is XML escaped
