Hello!
I have a VG400 ASR I'm looking to install in our environment using MGCP configuration. First type of VG like this I've tried. I'm used to the older 310, 320, and 204s. I'm setting up the VG400 using bridge interfaces to utilize two links to two different switches. These links pass two vlans. The upstream switch from the VG400 is a 9300 physical stack switch.
The network config seems to work. I get NTP. ISE works fine. I can ssh to the device to the IP I require. But I'm not ruling out something I may be missing on the network config.
For the VG config I'm doing all the things I've seen in the countless posts I've run across in community. TFTP source interface is right. The domain is configured on the VG, and as such, the device in CUCM is configured with mydevice.mydomain.com properly so the config matches what is being requested. I can even http to the server and view the device configs in a browser. I've restarted TFTP on both servers (two CUCM servers, 1 pub 1 sub).
I have two other VG 204s with similar configurations. The 204s are SCCP, but they use the same vlans. They also do bridge mode using BVI interfaces. They work great.
I don't have any ACLs or Firewalls in between blocking anything. I can reach the CUCM servers from the VG400 device just fine. The VG interfaces will register to CUCM just fine. I can see all 4 FXS ports register to CUCM in the GUI. When I debug mgcp on the VG400 I see packets sent and packets received. So I feel traffic is good.
I'm attaching the gateway config as well. Anyone been here and might have a suggestion? I've never had issues with VG configs like this before.
Thank you all for looking!

Based on the debug you posted, I am going to guess you have the gateway name defined in CM as "VG400-VO-RT01". The gateway must have an "ip domain name" defined. That means that you need to change the gateway name in CM to "VG400-VO-RT01.mydomain.com".
