Hi! I'm new here and I would like to know if someone may help me with my problem. First I have installed the app 3CXPhone from google play market. Second I gave the account datas from terrasip.net in the fields that I thought. For an example: Name: Some Name Display Name: MySammyName User: E-Mail Adress from the account of terrasip.net ID: ID from terrasip.net Password: Password from terrasip.net I'm out of Office: Yes External PBX IP: terrasip.net PBX port: 5060 STUN Server: stun.terrasip.net:3478 3CX Tunnel: No Proxy: No Save. No I look at the hook and all I see was registering and then Invalid account. Please help!!
