Follow-Me settings are just like a mini Ring Group, but it's tied directly to your extension. It's configured exactly the same way as a ring group, including the ability to use an announcement to alert people that they're being transferred elsewhere.
The dialplan has been structured such that any place where one might dial to ring an extension, the Follow-Me ringgroup will be engaged if it is defined. This means that from an IVR calling from outside and internally when dialing an extension you will reach the ring group in place of the extension. This behavior is enabled by simpling including the ext-findmefollow context ahead of the ext-local context any place that extensions are dialed.
There are other 'creative' uses of the Follow-Me function. At the simplest, you can simply put in the extension of the Follow Me number with a choice to go to its voicemail if not answered and you will be accomplishing exactly the same thing as if the extension was being dialed. However, you can now diverge with such simple things as changing your ring time to override the default, adding an announcement, going to an alternative voicemail or other destination if not reached, and of course adding multiple numbers and ring strategies when someone tries to call that number.
In addition to the settings for Ring Groups, the following options are available:
By default (not checked) any call to this extension will go to this Follow-Me instead, including directory calls by name from IVRs. If checked, calls will go only to the extension.
Checking this box is often used in conjunction with VmX Locater, where you want a call to ring the extension, and then only if the caller chooses to find you do you want it to come here.
This is the number of seconds to ring the primary extension prior to proceeding to the follow-me list. The extension can also be included in the follow-me list. A 0 setting will bypass this.
The following Ring Strategy is only available in Follow Me (but not for Ring Groups):
