English has simple rules + for deciding when to say "call" and when to say "calls", but other + languages have complicated rules which would be extremely difficult + to implement in the Asterisk dialplan language. + The correct sound file is selected by examining the + number and adding the appropriate suffix + to filename. If the channel language is + English, then the suffix will be either empty or "s". If the channel + language is Russian or some other Slavic language, then the suffix + will be empty for nominative, "x1" for genative singular, and "x2" + for genative plural. + Note that combining filename with + a suffix will not necessarily produce a correctly spelled plural + form. For example, SayCountedNoun(2,man) will play the sound file + "mans" rather than "men". This behavior is intentional. Since the + file name is never seen by the end user, there is no need to + implement complicated spelling rules.
