I JUST ACTIVATED THE REMOTE AGENT IN ANOTHER COMPUTER OUTSIDE OF MY NETWORK, I AM ABLE TO LOG IN, HOWEVER I GET AN CALL BUT HEAR NO SOUND AT ALL, CAN YOU PLEASE HELP.
The audio between RemoteAgent and the gateway is through UDP ports, which needs to be opened if there is router/firewall between them. For details, please see open firewall ports for SIP. If you are not sure about how to open these ports, please check the user manual of your router/firewall products.
