Installing same APP with different parameters on DX650

How can I install an APP on DX650 with different parameters ?

I have an APP with parameter 'IP' . I'd like to install this APP with 2 different IPs on different phones. So usually I would create 2 different Phone Services on CUCM with different name, same Service URL, different parameter and assign this services to different phones. But according to http://communities.cisco.com/community/developer/collaboration/end-points/dx-series/blog/2014/03/18/pushing-applications-to-your-dx650 'Service name/ASCII Service Name' has to be set to the package name of the APP. But that means I can create the service only once and use the APP only once.

Or am I wrong ?

Any help would be greatly appreciated !

Best regards,

I believe it is possible to pass parameters to the application via the Android 'Shared Preferences' mechanism:

SharedPreferences | Android Developers

You can pass the values by adding Phone Service Parameters when defining the IP Phone Service – the name of the param will be the exact name of the shared preference
