If I use this, can someone tell me what I should have under my outbound route for dial patterns?
(I have always used my own configuration which does not have anything for dial patterns for the handset configurations and it is all handled by the outbound route dial patterns.)
Nobody can tell you that per se. The phone dialplan and the pattern matching in your pbx outbound route are two different things. The phone dial plan basically configures a digit timeout and validation only. The outbound route patterns will be configured to handle numbers you intend to send out your trunk that is configured on that outbound route. Not everything your phone dials will even hit your outbound route though such as feature codes! So, do not even try to make them “match”.
