Sorry to bother you again, I found I was wrong in describing my problem. I found out that I sent the CiscoIPhoneExecute xml to the phone last time, not the CiscoIPhoneImageFile xml.
The CiscoIPPhoneExecute xml is like:
http://192.168.1.2:8080/test/push2phone.jsp?action=get"/>
And "http://192.168.1.2:8080/test/push2phone.jsp?action=get" returns the CiscoIPPhoneImageFile xml, like this:
Image Title goes here
Prompt text goes here
0
0
http://192.168.1.2:8080/test/pngs/attention.png
so when I send the CiscoIPPhoneExecute xml to a phone, the phone will display the file attention.png on the screen with the sound chime.raw, then I press the "exit" button, the attention.png on the screen disappears. But if I then send the CiscoIPPhoneExecute xml with the "http://192.168.1.2:8080/test/push2phone.jsp?action=get" that returns the CiscoIPPhoneImageFile that contains a different png file, for example "warning.png", the "attention.png" will appear for a short time during the time when "warning.png" is downloading, then "warning.png" appears. I have no idea why that happens. I don't want to see "attention.png" when I'm sending "warning.png". What can I do?
I've tried to directly sent the CiscoIPPhoneImageFile xml to a phone, everything goes well, no "cache" problems. but I have no idea how to add the sound "chime.raw". I want the png files to be sent like short messages with sounds. Please help!
Thanks a lot.
