Simultaneous ring

Simultaneous ring

Simultaneous ring is a feature of telephone networks and phone systems. Simultaneous ring is a special method for relaying a call. If a call comes in to a telephone extension and this extension has simultaneous ring enabled, all the configured extensions will ring at the same time. The subscriber can answer the call from any extension where the call is coming in. The first extension to answer will receive the call. Various providers offer the simultaneous ring feature on their analog and digital telephone networks and allow it to be customized. Phone systems often also support this feature. Phone systems execute simultaneous ring without having to set the network up for this feature.

Simultaneous ring as a telephone network feature

If the telephone network offers simultaneous ring, a subscriber can set up any other numbers to also ring at the same time. These can be cell phone numbers or connections abroad. The number of parallel numbers which can be configured for each extension may vary between providers. Cell phone numbers and numbers abroad and other number rangers may also be limited. When using simultaneous ring on a network, a call will only take up one voice channel when answered.

Setting up simultaneous ring via the phone system

Many conventional phone systems and modern cloud phone systems support simultaneous ring. Users are typically free to define if and how many internal extensions and external subscribers ring simultaneously when a call comes in. However, we should point out simultaneous ring on an external phone number will take up two voice channels on the phone system. The telephone first receives the incoming call and then forwards it to an external number via another channel.

Cost considerations for simultaneous ring

The cost of simultaneous ring can vary greatly. Although simultaneous ring on internal extensions typically does not result in additional costs, forwarding it to an external extension or a cell phone can result in significant additional charges. After all, in this case the call charges from the actual extension to the number the call was forwarded to apply to both execution on the phone system and on the telephone network, and are charged to the subscriber who set up simultaneous ring.
