Well, I have read through many posts and tried many things and have not had any success. So I firgued that a post of my own may be the only answer. I have installed my 3CX server software and can make internal calls to extensions between computers on the network using the 3CX software phone. I have setup a PSTN device with the default 10000 UID and PASS. I followed the configuration guide for the SPA3102 and I can not make outside calls. Here are the details that I think may help you experts to help me. Please let me know if you need anything else and thanks in advance for the help.
