Cisco Voice FXS Busy

I have a Cisco voip lab at home and I have one major problem, hopefully someone will be able to help me out or point me in the right direction at least...
I have a Cisco 2620XM CME router and VIC-2FXS card within a NM-2V network module. I have been unable to get a telephone thats connected to either of the FXS ports to ring.
I can make calls from either of the analog phones connected to the FXS card, voice communication establishes with the IP phones fine.
When I try and call the analog phones from the IP phones I get a busy signal (engaged tone, not a fast busy or re-order)
I cant work out why this is not working, Ive tried changing ring frequencys, phone cables to rollovers to straight through tip and ring to four pin with BT master socket adapter and without.

I can get both analog phone ringers to sound when using the command:
test voice port 1/1/0 relay ring on.

Please find running config and voice port summary below:

I think you need to set up an ephone like this:

ephone-dn 9
 number 109
 name analog phone 1

ephone 7
 mac-address 1111.2222.3333
 button 1:9
 type anl

Not sure this will do it, but I saw an example like this somewhere.

Thanks for the comment.

An ephone represents a physical ethernet (IP) phone, I only have 6 IP phones. If I connected a seveth this would map line button 1 on the phone to directly call ephone-dn 9 (109) essentially a short-cut or speed dial on ephone 7 instead of pushing buttons 1, 0 and 9.

Well I was looking at an example of an analog fax machine that was connected on an FXS port.  So you can call outbound because that is just using h.323, but inbound calls are processed by the CME, and basically my thinking is that you have to define a "fake" ephone, and assign that DN to it so that CME as a routing entry for the analog directory #.  That is how I interupted that example I sent you.  Obviously there is no MAC associated to the analog port, so a psuedo MAC was used.   I do a lot of work with CME, I just typically don't configure FXS ports.    My initial thinking would have been just add a DN like you did, and then CME can handle the routing, but since it wasn't working  I figured I would throw this out.  But this was a real example of a fax machine on an FXS port in CME.

That is also why the ephone has the type anl  - for analog.

you tried to reload the router?
remove the ephone-dn 9 and 10 and it will work directly.
