When using sequential forwarding the call is forwarded to the first (main) preset number which rings for a certain number of seconds (you set the desired length). If there is no answer within that time, the call is automatically redirected down the sequence to the second preset phone number. If the second number does not answer, the call is again forwarded and so on. Up to 4 numbers can be added to the sequence. If the call is never answered you have the option to send it to voicemail.
Here is how you can set up sequential forwarding:
1. Log in to your control panel with your email and password.
2. Click My Phone Numbers on the left side.
3. Click on the Settings Icon of the service line you want to change.
4. Select Call Forwarding tab and click Advanced Routing.
5. Click the orange Go to Rules button.
6. Click the green Create New Rule button.
7. From here, you can enter all the parameters you wish to add to your sequential forwarding rule. Enter a description, days of the week, start and end dates, and phone number to forward to.
8. Add additional numbers that will ring sequentially if the previous number does not answer. Click Save Rule.
