[Asterisk-Users] Pressing digits on SNOM phone results in letters on display

[Rana Dutt]

My SNOM 200 phone got into a funny mode where if I dial any digit, a letter
gets displayed and sent, so dialing no longer works. For example, if I dial
"9", the letter "w" gets displayed and sent when I press OK. How do I get it
out of this mode?
