[Asterisk-Users] Language setting

[Jeroen]

Have played with several languages in Asterisk -  by using the 
SetLanguage() command in the extensions.conf.
The scenario is that I do not want every caller to use the same 
language, although they do use the same extension.

E.g. H323 users can have a different language than SIP user. Read in 
several threads that the language can be set in the conf. files.
I have tried different syntaxes but it did not work -> what should I 
change (and where) in order to realise that all e.g. H323 callers will 
another language?

Thanks
Jeroen
