The presence of the chunking mechanism is likely an artifact of the particular HTTP stack on the device. Since it's valid HTTP, it may not be possible to get this easily changed (as a defect), though I would tend to agree consistency would be desireable (an enhancement.)
Where you may have a good point is the phone sending a chunked response to a HTTP/1.0 request...my reading of RFC 2145 is that it shouldn't work that way. Will investigate further.

Also can you confirm the firmware version of the 7925? Is this the latest version available on Cisco.com?

I am currently POST'ing a CiscoExecuteItem to various IPPhones. It works fine to all phones except 7925G's.
I have traced the response using wireshark and the 7925G's response is chunked whereas no other phones is.
I and using httpwebrequest and httpwebresponse in the .NET framework and for some reason this chunking is not be handled correctly from 7925G's.
I have tried sending the POST to the phone as http/1.0 to try and stop the phone chunking as this is only supported in http/1.1 but the phone still responds in http/1.1
Is this a configuration that can be changed on the phone to prevent this as 7925G's are the only phones which seem to do it.
When i perform a GET for DeviceInformationX on the 7925G's this responds normally(not chunked!)

I found the problem and corrected it;
The problem is when sending an ExecuteItem i was enclosing the URL and Priority with ' . this is accepted by desk phones but not the 7925G's. Strange but there it is. i have the admit thou the spec does say use " but my app had worked for some time on deskphone only when somebody threw a 7925G into the mix did this error happen. Thankyou for you help.
