Call forwarding
You can set up forwarding options for your SIP or virtual number (DID) incoming calls.
1) Now, let's assume you're waiting for an important call from your business partners in Moscow, Russia. They are calling to your Moscow virtual number (DID), usually you've been using VoIP phone in your office, but you are out of the office now and want to forward all calls to your mobile. It's very simple to arrange - just go to Call Forwarding section in your VoIPclub account settings, type your mobile number in the "Forward calls to" field, choose "Before call" option and click on Set Forwarding button. That's it!
2) Another example - if you're usually using your SIP at home or in the office, but you're sometimes leaving your premises for a short period of time you can set up your forwarding in a way, that calls will be forwarded to your mobile only in cases, when there's no answer on your SIP device. Again, proceed to Call Forwarding section, type your mobile number in the "Forward calls to" field and choose "No answer" option.
