[asterisk-users] voicemail usernames can't begin with "j" letter?

[Ricardo Carvalho]

Dear all,

I've configured Asterisk Voicemail, but after some tests I realised that 
when some call is sent to the voicemail of someone which username begins 
with "j" letter,  Asterisk gives me the error:


WARNING[5865]: app_voicemail.c:2412 leave_voicemail: No entry in 
voicemail config file for 'ohn'

(for a called user named john, for example)


Is this some kind of Asterisk bug, or am I skipping some configuration? 
How can I make things work fine?

Thanks in advance,
Ricardo.
