We’re expanding the reach of simultaneous ring beyond just sip trunking. You can now use this feature across a broader range of Telnyx voice applications, including programmable voice and Voice SDK (WebRTC) clients.


## What’s new

Register any mix of SIP endpoints or WebRTC clients under the same credentials and they will all ring together, no matter where the call starts. That includes:
- PSTN
- SIP trunk
- Programmable voice

Every active endpoint rings at once, and the first person or device to answer is instantly connected, enabling a more flexible and responsive call routing experience.



## Why it matters

**Fast response times**
Simultaneous ring delivers calls to all active endpoints at once, including softphones, desktop browsers and mobile clients. your team can answer the moment a call arrives, which reassures customers and shows you value their time.

**Shared access to numbers**
Instead of relying on one receptionist or device, your whole team can pick up incoming calls during business hours and mute notifications when they step away. that shared responsibility keeps calls moving and prevents overload.

**Real-time global coverage**
Distributed teams and international offices can share responsibility for phone coverage without altering your existing call flows, analytics or voicemail settings. Every call finds an available ear without complex forwarding rules.


## Getting started


1. [Sign up](https://telnyx.com/sign-up) or [log in](https://portal.telnyx.com/#/login/sign-in) to your Telnyx Mission Control Portal account.
2. Register each client with the same SIP credentials.
3. In Mission Control or through the Telnyx API, activate simultaneous ring for that credential set.
4. (Optional) Set an overflow rule. After a chosen ring time, route the call to voicemail, another ring group, or an IVR branch.
5. Test and Iterate: Use the built-in testing tools in the portal to simulate

**What's new:**
We’ve enhanced the Private PGW (PvT PGW) feature to support static IP address allocation. Now, every time a device connects to the wireless network, it will be assigned the same private IP address rather than a new one for each session.

**How it works:**

* The static IP is automatically assigned to a SIM when it’s added to a SIM group linked to a PvT PGW.
* If the SIM is moved to a different SIM group, the IP address is removed from the SIM.
* This ensures each device in a given group always receives the same IP address for every connection.

**Benefits:**

* **Consistency:** Devices are always reachable at the same IP, ideal for remote access, running servers, or firewall/port forwarding configurations.
* **Simplified network management:** Track and manage devices by their fixed IP addresses.
* **Improved policy enforcement:** Reserved services, permissions, and restrictions are easier to manage for individual devices.

**Availability:**

* All new PvT PGWs will include static IP allocation by default.
* To use this feature, customers with legacy PvT PGWs must create a new PvT PGW and move their SIM groups. Existing PvT PGWs will **not** be upgraded automatically, to avoid disrupting live services.



Private PGW now supports static IP address allocation
