Sip:provider mr3.5.1 is Now Available!

Sip:provider mr3.5.1 has been released!

We are excited to announce the general availability of sip:provider mr3.5.1, CE and PRO, a.k.a the new v3.5 version.

What’s the Sip:provider platform?

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 connects 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 signalling encryption, IPv6 support, fraud- and Denial-of-Service prevention. Another use-case is to act as a Class 4 SIP concentrator to bundle multiple SIP peerings for other VoIP services.

What’s new in Sip:provider mr3.5.1?

The most important changes for mr3.5.1 are:

  • Developed new sip:Carrier 3.x architecture
  • RTPEngine supports interface bridging now
  • Using Elasticsearch as main logs storage for sip:Carrier 3.x
  • Kamailio has been updated to version 4.1.6
  • Add numbers and names to prosody sipwise-vcard module
  • New REST API methods
  • Debian/Jessie basic preparations/cleanups
  • Kamailio uses Redis for concurrent calls tracking now

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. Also you can use our AMI (Amazon Machine Images) image or Docker container. For those of you using Amazon Cloud we provide the EC2 AMIs in the following regions: region us-east-1: ami-c647ffae , region us-west-2: ami-abe6aa9b , region us-west-1: ami-055f4a40 , region eu-west-1: ami-7e54f809 , region ap-southeast-1: ami-649fb936 ,  region ap-southeast-2: ami-15462b2f , region ap-northeast-1: ami-610d3b60 , region sa-east-1: ami-3da41020 .

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 mr3.5.1 from scratch.

For users of the SPCE mr3.4.x, please follow the upgrade procedure outlined in the Handbook. If you have customised your configurations using custom tt.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?

We are publishing 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 to pull requests. For development related questions, please subscribe to our SPCE-Dev Mailing-List at


We want to thank our CARRIER and 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 mr3.5.1 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!
