dialing out: Rings once then hangs up

Hello.


I have a callmanager 7 server at home with a Cisco 2621XM router to connect to the PSTN that I use for testing and experimenting (not following the CCVP path yet). I wanted to have this router routing my internet connection as well so changed the LAN IP address (along with all the other usual changes). I've changed the H323 gateway on the callmanager server in VMware and outbound calls work great, unfortunately outbound calls now hang up after one ring. I can't think what is causing this to happen and there is nothing (to me) glaringly obvious that is wrong so have hit a dead end.

Does anyone have any ideas?




Also not essential, but does anyone know how to resolve this error?

*Oct 31 15:33:34.584: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Fast
Ethernet0/1 (not half duplex), with Callmanager701.workgroup eth0 (half duplex).

I've tried the following command, set network nic eth0 100 full, but it returns executed command unsuccessfully. Doing a show network eth0 the mode is displayed as Auto disabled, full, 100MB/s. I'm guessing it is a problem with it being run in vmware?


Thanks.
