Work flow for DID

Technical explanation:

1. Let's say call comes through some Provider. The connection type is not important. So it could be PSTN/SIP/IAX2 whatever.
2. Call -> Provider -> PSTN/SIP/IAX2 -> Your Asterisk
3. Then call hits dialplan [mor] exten => _X.,1,mor:
4. Call -> Provider -> PSTN/SIP/IAX2 -> Your Asterisk -> MOR
5. MOR checks incoming DID with it's DB, if it's found, it sees where to route the call. In MOR GUI you can select to route DID to some special Dial Plan (CallBack, Calling Cards, Authorization by PIN/ANI) or some local device.
6. Local device in it's Call Flow can forward the call to:
   1. VoiceMail,
   2. another Local Device
   3. External number
7. So summed up, MOR can forward DID to:
   1. Dial Plan (CallBack, Calling Cards, Authorization by PIN)
   2. Local Device
   3. VoiceMail
   4. External Number
8. Call -> Provider -> PSTN/SIP/IAX2 -> Your Asterisk -> MOR -> (a or b or c or d)
