Hello Anoop,

I am not an rtpproxy expert. But I would suggest that you look into the error 
quoted above. This means that rtproxy can't bind to the respective port and or 
address. There are several possible reasons for that:

- this IP is not configured (correctly) on the server
- the port is already allocated to another process
- there is some other error in network configuration

Best regards,
