T1 CAS calls immediately dropped

Hi,

I've had some great luck from this forum before so I'll try again :).  I'm using a cisco 3825 gateway with a VWIC2-2MFT-T1/E1 connected to a dialogic d/240jct-t1  card in a windows server that is running a voicemail application.  There is a t1 crossover cable connecting the two.  I have call manager sent up 7 installed and working.

 

When I attempt to dial into voicemail I get dropped after several seconds.  Attached are the outputs of debug mgcp all, debug mgcp packets, debug vpm signal and the config.  From what I can see the call is making it through the gateway but is getting dropped after that.  I tried running ansrmt ( a dialogic demo voicemail system) to rule out my software as being the issue but I have the same problem.  To be completely honest I'm not sure if this is a routing / call manager issue or the voicemail server, hopefully the logs will show where I should be looking.

 

Thanks!
