sip:provider v2.6 Released

I am excited to announce the general availability of sip:providerCE v2.6 and sip:providerPRO v2.6!

This release marks a big milestone, because it’s the first open source turn-key platform with full presence support to provide Skype-like services.

What’s the sip:provider platform?

sip:provider PRO Architecture Overview

The Sipwise sip:provider platform is a highly versatile open source based VoIP soft-switch for ISPs and ITSPs to serve large numbers of SIP subscribers. It leverages existing building blocks like Kamailio, Sems and Asterisk to create a feature-rich and highly performant system by glueing them together in a best-practice approach and implementing missing pieces on top of it.

Sipwise engineers have been working with Asterisk and Kamailio (and its predecessors SER and OpenSER) since 2004, and have roles on the management board of Kamailio and are contributing to these projects both in terms of patches and also financially by sponsoring development tasks. The sip:provider platform is available as a Community Edition (SPCE), which is fully free and open source, and as a commercial PRO appliance shipped turn-key in a high availability setup.

The SPCE can provide secure and feature-rich voice and video communication to end customers (voice, video, instant messaging, presence, buddy lists, screen sharing, remote desktop control) and connect them to other SIP-, Mobile- or traditional PSTN-networks. It can therefore act as open Skype replacement system, traditional PSTN replacement, Over-The-Top (OTT) platform and also as a Session Border Controller in front of existing VoIP services in order to enable signaling encryption, IPv6 support, fraud- and Denial-of-Service prevention. Another use-case is to act as a Class4 SIP concentrator to bundle multiple SIP peerings for other VoIP services.

How do I test-drive the new version?

As usual, we’re providing both a VMWare Image and a Virtualbox Image for quick evaluation testing. Check the relevant section in the Handbook for detailed instructions.

If you want to test the sip:provider together with the Jitsi client for getting all the shiny unified communication features, make sure to use the latest nightly build of Jitsi, otherwise it will most likely not work as expected!

The sip:provider also supports Jitsi autoprovisioning, the URL is:

https://<platform-ip>/jitsi?user=${username}&pass=${password}&uuid=${uuid}

How do I install the new version or upgrade from an older one?

For new users, please follow the Installation Instructions in the Handbook to set up the SPCE v2.6 from scratch.

For users of the SPCE v2.5, please follow the upgrade procedure outlined in the Handbook. If you have customized your configurations using customtt.tt2 files, you must migrate your changes to the new configuration files after the upgrade, otherwise all your calls will most certainly fail.

Acknowledgements

A big thank you also to all the developers of Kamailio and SEMS, who make it possible for us to provide an innovative and future-proof SIP engine as the core of our platform! And last but not least a HUGE thank you to the Sipwise developers Mika, Andrew, Jon, Richard, Christian and Min, who worked insanely hard to create this release. You are plain awesome!
