Voicemail settings for Vamos mobile are determined on the PBX, not on the mobile device/network.
To turn on voicemail for Vamos mobile take the following steps:
Activate User’s voicemail on the PBX
Include the voicemail box in the Personal dial plan of the user
Once set up, recorded voicemail messages will be emailed to the user as audio files. Alternatively the user can also 'dial in' to his voicemail box via number 1233.
To turn off the voicemail just deactivate the User’s voicemail option on the PBX.
Using the Voicemail speed dial in the Mobile device’s dialer will not work. The user actually has to call 1233.
