VVX 600: cipherSuite not accepted

I'm trying to assign a cipher suite to a Polycom VVX 600 by means of XML. The XML download from the FTP server works, as all other settings are accepted by the phone.




Relevant portion of XML file:


<polycomConfig xsi:noNamespaceSchemaLocation="Config/polycomConfig.xsd">
<device device.auth.localAdminPassword="****" device.auth.localAdminPassword.set="1" device.baseProfile="Lync" device.baseProfile.set="1" device.prov.lyncDeviceUpdateEnabled="1" device.prov.lyncDeviceUpdateEnabled.set="1" device.prov.tagSerialNo="1" device.set="1">
 <device.sec.TLS.profile device.sec.TLS.profile.cipherSuiteDefault1="0" device.sec.TLS.profile.cipherSuite1="ALL" device.sec.TLS.profile.cipherSuiteDefault2="0" device.sec.TLS.profile.cipherSuite2="ALL"/>
When I check in the Web interface of the phone, I can see, that the cipher suite is still set to default, so my overrides are not applied.
Manual override would work, but since I'll have to provision quite a lot of phones, this has to be automated.
Any clues?
Thanks in advance.
