Dear all, I am new to FreeSwitch. I am trying to use an external SIP profile for connecting ouside my LAN I create a SIP account on iptel.org. To add a new gateway, I created a file and saved into the External folder <include> <gateway name="custom"> <param name="username" value="MY_USER_NAME"/> <param name="password" value="MY_PASSWORD"/> <param name="realm" value="iptel.org"/> <!-- iptel.org requires a 'proxy' parameter --> <param name="proxy" value="sip.iptel.org"/> </gateway> </include> I have given the username and password which I got after creating an account at iptel.org. Now, after launching FS CLI, I run a "sofia profile external restart reloadxml" which is giving me message "Invalid Profile [external]" I am not able to make up what is the problem. I have some understanding of Networking. When i tried to find this issue on internet I found that this could be related to: 1. Is this a problem because of NAT? or Port Forwarding which I need to do? Please give me some clue to debug the issue. Thanks Ankit -- Life is like a rose its upto u feel it as its fragrance or thorns
