The h323-gateway voip bind srcaddr command defines what address the gateway uses for RTP connections. You have 10.10.110.1 being used for Gatekeeper (RAS) signaling, and 10.10.200.3 being used for CUBE because of the h323-gateway voip bind srcaddr command. If you want everything to appear as 10.10.110.1, do a "no gateway", remove the bind command from the fastE interface, and apply it to lo0.

I am puzzled with the configuration on the ipexpert soultion guide. on HQ int lo 0 i.e. 10.10.110.1 here is the config: int lo 0 h323-gateway voip h323-gateway voip id UCM 10.10.110.1 1719 h323-gateway voip h323-id CUBE So, technically the lo 0 is having the gateway configuration, but the h323-gateway bind is on the int fa 0/0.20 sub interface of hq-router. isn't the call flow should be CUCM to cube(10.10.110.1), and then cube(10.10.110.1) to cme. but the call flow is appearing as: cucm ----> 10.10.200.3 10.10.200.3 --> cme. how could it be possible to have 10.10.200.3 acting as gateway having the gateway config on interface lo 0. any advice on this matter is much appreciated. thank you krishna.
