[asterisk-users] Can not check voicemail from outside

[Joseph]

I've setup an internal access through DISA  as below but I get a
misleading announcement (no messages) in my mailbox. 

[disa]
exten => 123,1,Answer
exten => 123,2,DigitTimeout,8
exten => 123,3,ResponseTimeout,30
exten => 123,4,Authenticate(xxxx)
exten => 123,5,DISA(xxxxxx|disa-access)

[disa-access]
include => tollfree
include => outgoing-plain_voip
include => voicemail

I can "get-in" after authentication, I enter my voicemail extension
number; I'm asked for "mailbox number" "password" and get an
announcement I have no messages waiting, even though there are two
messages in my mailbox.

When I dial my mailbox number from internally asterisk tells me I have
two messages.
Why I get a misleading announcement when I dial-in over DISA?
