VG80-20 cannot register to GK successfully, and GK shows that VG80-20 is requesting the IP of another GK.
Check the configurations of VG80-20:
gk-id avs gk-addr 184.108.40.206 1719
gw-address ip 220.127.116.11
gk-add is correct in both configuration and port number.
The gk-id avs is in lower case, but it is upper case in GK, so the problem could be solved by modifying the avs to AVS.
The probabilities include:
1. GK is not configured with the permission for registration of VG80-20 to GK.
2. Area is configured falsely.
