Rae,

If you could go more into detail as to what error response x-lite is giving to you. From the information you listed, you have used the correct settings. Be sure to use the sip.voipwelcome.com address.

Also, what version of x-lite are you running? If you have firewall software or antivirus software running, be sure it's not blocking the x-lite application from sending/receiving.

What type of network connection are you using? I ask this since you stated you are traveling. It's possible the port is blocked on the network.

Thank You,
Joseph
