Connect DID to analog phone through VG224

Hello,

We currently have 100 DIDs from our service provider.  Most of these are used as direct lines for our users, and are forwarded to directory numbers through our callmanager.  I would like to use some of these as analog fax lines if possible.  I have added the translation patterns in the callmanager to convert the DID to a directory number.  I then have the directory number attached to a fxs port (2/4) through our vg224 gateway.  The vg224 is connected to a punchdown block with a 25 pair cable.  I punched wires down from the block into a phone jack, and then connected a phone.  Now, when I try to call the number, I get a fast busy signal.  When I pick up the phone connected to the block, I get no dial tone, but it does show a call time when I do a sh voice call on the vg224.  The strange this is that it shows the call on two ports (2/4 and 2/5).  Any ideas?

Any help will be much appreciated.

Thanks.

Are you sure you punched down the wires on the right pair on the 66 block? Sounds like you have one wire on each pair.
Make sure the directory number is assigned a css.

I tried rewiring it several times, and although I repeated the same thing, it seems to be working on a single line now.  I still don't get a dial tone though, and I still get a fast busy whenever I dial the phone number.  The directory number does have a css.

Is the VG224 registered to the CM?

I'm very new to Cisco Voip, so please excuse me if I sound stupid here.  When I go to gateways in the callmanager, the vg224 is listed there, and I can change port settings from there, so I'm assuming yes it is registered.  Is there something else I need to check to make sure it is?

What version of Call Manager?
If you drill down into a port is there a line assigned to the port and is that line in a partition, and does it show as Registered with call manager <ip address of CM> ?

Version is 5.1.2.3000.
When I click on the port I'm trying to test, Line 1 is there, and it is the directory number I want, but the Registration and IP Address are both Unknown.  I assume that means this port isn't registered with the callmanager then.  How would I go about registering it?

Really depends on how the VG224 is configured. MGCP gateway, h.323 gateway? STCAPP sccp ports?
This document might help.

It's configured using MGCP with mgcpapp ports.  Looking at how it was originally set up, everything is basic.  I see the ccm-manager configuration is present.  Here is the mgcp config with one of the ports:
!
mgcp
mgcp call-agent CCM 2427 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
mgcp rtp unreachable timeout 1000 action notify
mgcp modem passthrough voip mode nse
mgcp package-capability rtp-package
no mgcp package-capability res-package
mgcp package-capability sst-package
no mgcp package-capability fxr-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp fax t38 inhibit
mgcp rtp payload-type g726r16 static
!        
mgcp profile default
!        
!        
!        
dial-peer voice 99920 pots
 service mgcpapp
 port 2/0
!        

Is there anything here that you can see is wrong?

Seems kind of silly now actually.  I added the line: ip host <name of ccm> x.x.x.x.  After that, the gateway showed as registered in the callmanager and any call I made to the DID made the attached phone ring.  Thanks again for your help.
