I want to set up a DID number that users can call from outside, enter an extension and leave a voice mail. Rather than calling an extension, letting it ring until voice mail picks up. Internally, we dial * and the extension to go direclty to someone's voice mail.
Route the call to a call handler and by default it will allow users to enter extensions to be transferred to. If you don't want it to ring 4x after the transfer off the call handler, you can change the behavior on the subscriber's call transfer settings to go directly to greeting.
Hope that helps,
