I want to make outgoing calls with different numbers
You can make calls with different phone numbers using a Cisco. A Cisco SPA303 has three lines available for this, and a Cisco SPA504G has four lines. A VoIP account can be set up on each of these lines, and for each VoIP account, you specify the outgoing number.
You can easily set up the first line of the Cisco as described above. The other lines are set up as follows.

Assigning the correct number to outgoing VoIP account lines.

How do I make calls through the correct line?
Enter a phone number and press the correct line on the right side to make calls with the different numbers.
I keep getting an annoying beep tone during calls.
This could mean you're receiving a call waiting notification on one of your other lines. Click here to learn how to turn it off.
