REQUIREMENTS
Voicemail name must be the same of the sip name (e.g. john.doe).
The voicemail password must be numeric (e.g. 0000).

HOW IT WORKS
Access to voicemail can be handled by using ivr script and a custom application (VoiceMailMain).
You need to set two different dial plans:

An internal DID that need to execute the custom application (VoiceMailMain). The application VoiceMailMain allows you to manage the voicemail messages.
An external DID to access to the ivr script. The ivr asks the voicemail extension you want to check and performs the query to xcally db to retrieve the voicemail name (sip name). Then the call goes to the internal dialplan to execute the VoiceMailMain application.
