Good job on the dial plan .......
Sometimes they get a little tough as we learn how they operate !
I have an additional question. Now that the NBX is routing the DID properly, will it auto generate the DTMF tones out the analog port or is there an additional dial plan config I need to add?
Not exactly sure what you ask but :
when the call is first set up or made, the digits are internal to the NBX and the tel . Once the connection is made , whether it is an inbound or outbound call ( in an offhook state ) You will hear the DTMF tones over the line . This is called I believe out of band signaling . So the tel inbound will generate the dtmf or the tel on an outbound call will generate the dtmf .
