[Freeswitch-users] voicemail_greeting_number - question

Hi ALL, I am playing around with VM and want to play user recorded greeting instead of default one. I've scaned wiki Mod_Voicemail and found proper parameter "voicemail_greeting_number". Unfortunately there is a lack of example hence i dont know if it is already working. Aforementioned param was placed in /conf/directory/default/1000.xml file (param name="voicemail_greeting_number", i tried many values) The effect is that the default greeting is played. Is this param embeeded into FS right now? How to use it? Is there any other place I should do the changes? I am running FreeSWITCH Version 1.0.trunk (16456). Thx in advance. Maciej
