[Asterisk-Dev] Voicemail problem

[Sheetal B]

Hello All,
                We have VOIP running on Asterisk.
 We are having problems with voicemail. As in when a customer is
having more than 1 phone numbers and he wants to check his mailbox
when he dials in to check his voicemail it should pick the primary
mailbox but it is picking up the wrong phone extension and verifying
the primary mailbox password with that extension which gives an error
password not verified.
Help Appreciated
Thank you,
