New Sip:provider mr3.6.1 is Now Available!

Sip:provider and Sip:CARRIER has been released!

We are excited to announce the general availability of Sip:provider mr3.6.1 (CE and PRO) and Sip:CARRIER mr3.6.1.

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 Sip:provider mr3.6.1?

The most important changes for mr3.6.1 are:

  • Central config management on SIP:Carrier 3.x installations
  • General system cleanup before the next LTS release
  • Full migration from Apache to Nginx
  • SOAP API is deprecated for now
  • Central storage for all SSL certificates under /etc/ngcp-config/ssl/
  • Old Subscriber interface has been disabled
  • New Subscriber interface has been separated from ngcp-panel Admin interface
  • XMPP Multi-user Chat (MUC) is enabled in Prosody
  • CloudPBX: Implement park/unpark via VSC: *97* to park and *98* to unpark the call
  • CloudPBX: Add auto-provisioning for Panasonic devices
  • New REST API methods are now available (e.g. search for customers by external_id, resellers can manage call forward and fax server settings, add credits via REST API and more)
  • CDR-exporter: dynamic field selection and sftp transfer
  • Custom fields gpp0-gpp9 can be stored in CDR tables
  • SSLv3 is completely disabled (CVE-2014-3566)

Important upgrade notes:

  • Apache is not going to be installed on new installations since mr3.6.1, while we keep it installed during the upgrade. Feel free to remove it manually using “apt-get purge apache2” if you do not use it. Otherwise, please migrate your virtual hosts to Nginx and remove Apache.
  • SOAP/XMLRPC API has been migrated to Nginx and disabled by default. They are deprecated, for now, please switch your components to REST API. Still, SOAP/XMLRPC API are available and can be enabled in config.yml (ossbss->frontend:fcgi). They are going to be deleted in the upcoming release(s).
  • Old Subscriber self care interface is deprecated and has been disabled by default. New ngcp-panel based Subscriber interface has been separated from ngcp-panel Admin interface and available on the old port 443. System owners can separate and control the network interfaces where Subscriber and Admin panels are available (please use web_ext type to assign Subscriber self care interface in network.yml and web_int for Admin interface). IMPORTANT: Admin ngcp-panel interface listens on localhost only by default, please assign “web_int” type to appropriate network interface in /etc/ngcp-config/network.yml and run ngcpcfg apply.
  • All default SSL certificates described in config.yml were copied to folder /etc/ngcp-config/ssl for central backup/management. Please check and move personal SSL certificates to new storage for further usage.

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: us-east-1: ami-0033a668, us-west-2: ami-5b165c6b, us-west-1: ami-2feff96a, eu-west-1: ami-8ad661fd, ap-southeast-1: ami-8298bbd0, ap-southeast-2: ami-59294763, ap-northeast-1: ami-0b9aa20a, sa-east-1: ami-df63d5c2.

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 mr3.6.1 from scratch.

For users of the SPCE mr3.5.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 mr3.6.1 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!
