What Is a Ring Group and How Should It Be Configured?

 A ring group is a telephony feature that allows an incoming call to be routed to multiple extensions or devices simultaneously or in a specific sequence. It’s commonly used in call centers, support teams, or departments where multiple agents can answer the same call.

For example, when a customer calls a support line, the ring group can ring all available agents at once, and the first one to pick up handles the call.

Can I configure a ring group by installing Zoiper on multiple devices with the same SIP account?

 No. You should never register the same SIP account on multiple Zoiper clients in an attempt to simulate a ring group. This is a common mistake and leads to serious issues:

• Zoiper does not native SIP call forking, meaning it cannot properly handle simultaneous incoming calls to multiple devices using the same account. This should be done by the PBX/ server of the service provider.

• ⚠️ Call instability: You may experience dropped calls, missing audio, failed registrations, or one device overriding another.

• Security risks: Multiple registrations with the same credentials can trigger SIP authentication errors or lockouts.

 Who should configure the ring group?

Ring groups must be configured by the service provider or PBX administrator — not by the end user or within the softphone itself.

This setup is handled at the server level (e.g., Asterisk, FreePBX, 3CX, etc.) where the PBX can manage call routing, availability, and failover logic. The softphone (like Zoiper) simply registers to a SIP account and receives calls as directed by the PBX.
