sip:provider mr3.3.1 Released

We are excited to announce the general availability of sip:providerCE mr3.3.1 and sip:providerPRO mr3.3.1, aka the new v3.3 Version.

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 high-performance 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 provides secure and feature-rich voice and video communication to end customers (voice, video, instant messaging, presence, buddy lists, file transfer, 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.

What’s new in mr3.3.1?

The most important changes for mr3.3.1 are:

  • NGCP-Panel

    • Feature-Completion of the REST-API at /api – over 40 new API resources available
    • New customer preferences mechanism to provision customer-wide preferences – currently ncos and block preferences
    • Subscriber Profile Handling – limit subscriber preferences (features) by assigning feature profiles
    • Password Auto-Generation – control password policies and auto-generate them
    • Password Recovery – Let users reset passwords via CSC
    • Email Notification on subscriber creation and password reset
    • Allow reseller rebranding of CSC and admin panel via CSS overrides
    • PDF Invoice Generation – customized via SVG templates in online editor
    • Cisco SPA Directory Service (CloudPBX only)
  • SIP/RTP Core Enhancements

    • Allow to disable 100rel support
    • New bypass_rtpproxy preference to bypass rtpproxy for subscribers in same LAN
    • Possibility to enable/disable SIP INFO method
    • Rename mediaproxy-ng to rtpengine
    • Full DTLS transcoding support for WebRTC
    • New option dos_whitelisted_subnets for flexible DoS mitigation control
    • Implement serial forking based on q-value
  • General System Fixes and Enhancements

    • New HA watchdog to recover after split-brain (PRO only)
    • Lots of CloudPBX enhancements
    • Preparation of systemd support

How do I test-drive the new version?

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

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 mr3.3.1 from scratch.

For users of the SPCE mr3.2.x, 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.

How can I contribute to the project?

Over the last months we’ve started to publish our software components at This is still an on-going effort, which is done on a component-per-component basis. Please check back regularly for new projects to appear there, and feel free to fork them and send us pull requests. For development related questions, please subscribe to our SPCE-Dev Mailing-List at

What’s coming up next?

The mr3.3.1 release contains a huge number of new features considering the short release cycle. For the upcoming mr3.4.1 we’re preparing the system for a new LTS version, so it will mainly be optimization and bug fixing. Nonetheless, we’re currently working on Event Detail Records (compared to Call Detail Records), so you could charge customers based on the features they are using instead of the calls, allowing for attractive product modeling. Also, there will be some further enhancements to the REST-API, so any feedback on the current state is highly appreciated, as it is the first version we consider stable and feature-complete. The SOAP/XMLRPC API does not receive any new features anymore, so this is a good time to consider switching to the new API.


We want to thank our PRO customers and the SPCE community for their feedback, bug reports and feature suggestions to make this release happen. We hope you enjoy using the mr3.3.1 release and keep your input coming. A big thank you also to all the developers of Kamailio, Sems and Prosody, who make it possible for us to provide an innovative and future-proof SIP/XMPP engine as the core of our platform! And last but not least a HUGE thank you to the Sipwise development team, who worked insanely hard to create this release. You are awesome!
