This feature is controlled in the ComPBX User Panel.
The VMX (Virtual Machine eXtension) locator allows for advanced control of a user's voicemail system. It is somewhat similar to the Follow Me feature; however it gives callers more control. In essence, the VMX locater is a mini-IVR (interactive voice response) for voicemail.
When a caller reaches a user's VMX Locater, they are presented with a recorded message. This message would indicate to them that there are options in addition to simply leaving a message. Typically, VMX Locater voicemails would give callers the option of leaving a message OR attempting to contact the intended party. VMX Locater can be configured to work with 'unavailable' and/or 'busy' voicemails.
For example, a caller reaches your voicemail and is given the option to: press 1 to call your mobile, press 2 to reach the Melbourne office, press 0 to reach reception, or leave a message. This ensures that the caller is able to contact an appropriate party should they want to, or simply leave a message.
