Got it. The single instance where I saw a string on the display was when I called my telco's 
technical support.

Too bad, I was already dreaming of offering some customers a few nifty features, like greetings, 
email addresses for further contacts, booking confirmation numbers for hotels, etc...

I shall still go through all the charset options to see whether there is any effect. Meanwhile I 
managed to get a pcap trace of a calling device and the display element is not at all present. I 
guess they are filtering it out.

Thank you, Richard.
