Sip:provider mr3.7.2 Has Been Released

Sip:provider  mr3.7.2 is now live!

We are excited to announce the general availability of sip:providerCE mr3.7.2 and sip:providerPRO mr3.7.2.

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 Class4 SIP concentrator to bundle multiple SIP peerings for other VoIP services.

What’s new in mr3.7.2?

The build mr3.7.2 contains the set of fixes for release mr3.7. No new features added to mr3.7.2. See the full list of changes at the end of the announce.

How do I test-drive the new version?

  • AMI ID for region us-east-1: ami-be451fd6
  • AMI ID for region us-west-2: ami-e3d3f0d3
  • AMI ID for region us-west-1: ami-cf59bd8b

  • AMI ID for region sa-east-1: ami-cf3d84d2

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 mr3.7.2 from scratch.

For the users of the previous version of the SPCE, 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?

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

What’s coming up next?

The mr3.7.2 build is stabilisation/bugfixes build, so contains no new features. We are preparing some exciting new features for the upcoming mr3.8.1. Also, there will be some further enhancements to the REST-API, so any feedback on the current state is highly appreciated. The SOAP/XMLRPC APIs have been migrated to Nginx and disabled by default in the previous build mr3.7.1. You may switch it on using config.yml setting ossbss->frontend:fcgi, but those obsolete APIs are going to be deleted in the upcoming release(s).


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 mr3.7.2 build 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!
