[Asterisk-Users] asterisk voicemail question

[Tofik Suleymanov]

Hello list,

When new voicemail comes and i pick up the phone i hear special tones 
indicating that the new voicemail arrived.I've never had any problems 
with this feature, but several days ago it begin to behave strangely:
1. new voimcemail arrives, but i dont hear the special indicating tones 
when picking up the phone
2. there is no new voicemail (checked mailbox on filesystem), but when i 
pick up the phone i hear speial tones indicating that there is a new message


is this a known issue ?
