It is a bit strange that it routes to a hunt and then takes a coverage path.
It should be the opposite: the call should follow a coverage path and the coverage path can lead to a hunt, extenstions, vdn's, remote numbers etc.
When a call is not answered, the system will check if a coverage path is defined (you can see the number in the station screen behind field COVERAGE PATH 1 or COVERAGE PATH 2).
In general it will follow cov path 1 by default.
Use the command: DISPLAY COVERAGE PATH xx to see the details of the cov path.
The coverage path has 6 coverage points (bottom of the screen).
The call will first go to the number mentioned in point 1, if this fails it will send the call to point 2, then point 3 etc.
The number of a point can be:
- an extension : just a number => exp: 1234
- a hunt group : h + huntgroup number => exp: h1
- a vdn number : v + vdn number => exp: v9876
- another cov path: c + cov path number => exp: c7
- the attendant: attd
- a remote number: r + remote number => exp: r5
Normally a hunt group pointing to the voice mail is already defined. Use the command: LIST HUNT to see all the hunt groups created in your system.
In general Avaya uses hunt 99 as the hunt to the voice mail system. It will mention AUDIX.
Change the coverage path of the station (command: CHANGE COVERAGE POINT xx) and add that hunt as last point.
So the last point should be "h99".
This is not point 6 but the last point you use. h99 can be assigned directly to point 1, if you want the call to go directly to the voice mail.
Note: make sure that hunt numbers are always placed in the last point, as they will always "answer" the call.
Hope this helps....
