Each extension can forward to a maximum of 15 phone numbers.
Each number is dialed in order for the number of seconds you specify. Grasshopper defaults to 40 seconds (10-12 rings; the average amount of time it takes for people to pick up). If you would like to shorten this select Edit next to the forwarding number and change the number of seconds there.
Keep in mind, the more phone numbers you have, the longer the caller will be on hold if your account is set up to ring until somebody picks up.
If you would like calls to ring phone numbers simultaneously, please check out our Call Blasting feature HERE.
