Hi! 
 
I have a phone model 7912 which is out of sale and support. I had a problem with displaying a russian language at this model. I had solved it by changing an output xml encoding from UTF-8 to windows-1251. But now i am run into another problem:
 
1. I send an CiscoIPPhoneMenu object to phone
2. Item in this menu contains a QueryStringParam with russian symbols. Example:

  <MenuItem>
    <Name>Второй</Name>
    <URL>QueryStringParam:param27=Второй</URL>
  </MenuItem>
3. User select this item and submit it.
4. Server receive url with param: '&param27=??????'.

 
I think i can solve this problem in two ways:
 
1. Change phone encoding. But i dont find any way to do this.
2. Try to apply URL encoding to QueryStringParam.
 
Preferred method, of course, change phone encoding. Is this possible?
