For each Extension I can set a forward rule. If I do not answer calls within: 20 sec then I forward to mobile. But which trunk and Outbound rules are used for doing this forward call? And which CallerID is send along? The Trunk CID or Extension CID? From which extension? I understood that to be able send the original caller ID along with the forward call that I need a provider that support this function. I noticed that the Trunk has several Outbound Parameters that can be set to "OriginatorCallerID" but I think that is all useless unless the providers supports the function, right? Also this 20 sec answer time: this Extension setting is in the Internal calls section, but I suppose it is also used for the External calls? There is says 'after timeout....' so I think this 'timeout' means also this 20 sec from Int. Calls, right?
