[Freeswitch-users] password for voicemail retrieval

Hi, Can anyone please guide me on how to set password for voicemail retrieval? Currently voicemail password is being picked from dir_users table. But I don't want to pick from that table. I either want to pick from other table or I want a default password to be set as like vm-password. Instead of creating a xml for each user in conf, can I create just 1 xml and Can I give 'vm-password' once so that for all ids this will be looked? If not can you please tell where should I change in mod_voicemail.c file so that it does not look in dir_users for voicemail. Can anyone please guide me. Regards, Archana
