Sequential Ringing is an advanced form of call forwarding. Unlike traditional call forwarding, sequential ringing goes to multiple phones, and can be programed with specific rules. Sequential Ringing is a great tool for business, because business associates only have to know one number to reach you.
When sequential ring is activated, an inbound call will ring one phone, then another, and another, until the call is answered. The most common ring sequence is to route a call from a desk phone to a cell phone to a home phone, then to the voicemail box. But, there are many variations. Many, but not all, business VoIP providers allow forwarding to up to three phones and that is how they define a “user” for billing purposes. The user configures how many times the phone will ring before moving on to the next phone. The voicemail box is usually last because it will definitely answer the call.
