What is SIP Server as a Service? SIP Server as a Service – a cloud-hosted SIP service enabler

SIP Server as a Service is a cloud-hosted SIP service enabler. It includes all you need from a SIP infrastructure to get your SIP devices, such as cameras, IoT devices, phones, doorbells, elevators etc, online and ready to use.

Our serverless and cloud-based service does all the tasks included in setting up and maintaining a complete SIP infrastructure, allowing you to put all focus on your service or application.

SIP Server as a Service provides the setup of SIP registrars and user databases, SIP proxies, media relays and NAT traversal mechanisms. It also takes care of all those regular headaches and issues with SIP device end-to-end connectivity, reliability and security.


How does SIP Server as a Service work?

The SIP Server as a Service acts as a SIP registrar and a SIP proxy as well as it implements hosted NAT traversal for all your signaling and media flows should it be required. With the SIP service, you can easily register your SIP devices and start sending and receiving SIP and media traffic within minutes.

You can also connect WebRTC based SIP applications. Click on the image to view full size.

SIP device accounts can be created and managed using standard RESTful API calls or by manually accessing the customer web portal. Once the accounts are created your SIP devices can authenticate, register and setup sessions and calls end-to-end. The service will take care of your end-to-end connectivity in a reliable and secure way. Additional APIs can be used to monitor SIP device status and activity as well as to retrieve logs and statistics.

A device monitoring API is provided to listen for SIP registration and dialog state change callback events. The monitoring API can be used to develop applications showing if a device is on-line or in a call.

SIP Server as a Service will apply signaling and media encryption and, if needed, hosted NAT traversal to make sure your SIP devices are always connected and ready. Your end-to-end SIP service is now being delivered as expected.

SIP devices may be connected to the traditional telephony world to place and receive phone calls thanks to the built in bring-your-own SIP trunk functionality.

All traffic between your SIP devices and the SIP Server is encrypted and authenticated using well-proven Internet encryption technologies.

Devices that encrypt signaling using SIP/TLS or SIP/Secure websocket and media encryption using DTLS/SDES-SRTP are extra well protected. For devices not supporting this we connect your network using an IPSEC VPN connection. For simple initial tests you may even use unencrypted connections. All data is stored encrypted in our systems.

The SIP Server as a Service is fully managed by which means that you don’t need to learn and install any new software or take care of any infrastructure. The platform is built to meet the highest security standards and personal data is processed in compliance with GDPR regulations.

The SIP service is designed for mission-critical applications, meaning it is deployed on a geographically redundant infrastructure to always be available.

Benefits of the SIP Server Service

Everything runs in the cloud

No need to setup, run or maintain a SIP infrastructure. Just configure the SIP user accounts using our simple API, configure your devices and start deploying your service.

Scalability & Reliability

Grow as you go with full focus on the service you deliver. Most of the services out there has an upper limit on how many devices you may register. Our service is built for scale without limits.

Hosted NAT & Firewall Traversal

No need to care about common SIP and media problems related to NAT and firewall traversal; all of this are taken care of. When required, media will be anchored to make sure the customer end-to-end session experience remains.

SIP trunk connectivity

The SIP trunk functionality allows calls to be routed to and from the ordinary phone network or to connect an on-prem system.

Avoid codec mismatching ​

Transcoding from one codec to another is supported. This becomes valuable in case you have SIP devices supporting only codec X and your trunk provider only supports codec Y.

Pay for what you use

The web portal provides an overview of service usage, and as for all other functionality the data is accessible using APIs. Our micro service-based design enables you to pay only for what you use.

Out-of-the-box security

No need to worry about eavesdropping or manipulation of SIP or media traffic since all traffic between your SIP devices and the SIP service is encrypted and authenticated using well-proven Internet encryption technologies.
