Sip:provider mr3.7.1 – Released!

Sip:provider mr3.7.1 is now live!

We are excited to announce the general availability of sip:providerCE mr3.7.1 and sip:providerPRO mr3.7.1.

What’s the sip:provider platform?

The Sipwise sip:provider platform is a highly versatile open source based VoIP softswitch 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 mr3.7.1?

The most important changes for mr3.7.1 are:

  • Call queues module for Cloud PBX
  • Panasonic and Yealink IP phones auto-provisioning
  • REST API: add filter for API/calls
  • Provide pre-recorded ngcp-prompts in multiple languages and a preference to select the language
  • Support separate NCOS type for Call Forwarding
  • Implement To header manipulations using outbound_to_user preference
  • New modes for handling the extension dialled behind the main number using preference extended_dialing_mode
  • Improved sip:carrier system deployment using PXE boot and apt-proxy cache
  • Improved sip:carrier system management using klish and SNMP monitoring
  • Improved collection of call counters in redis
  • Backported new Linux kernel 3.16+62~bpo70+1 as a part of mr3.8 LTS preparation

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. For those of you using Amazon Cloud we provide the EC2 AMIs in the following regions:

  • AMI ID for region us-east-1: ami-04611f6c
  • AMI ID for region us-west-2: ami-7b0d534b
  • AMI ID for region us-west-1: ami-439a8406
  • AMI ID for region eu-west-1: ami-8bef6cfc
  • AMI ID for region eu-central-1: ami-cc5b68d1
  • AMI ID for region ap-southeast-1: ami-c08ba392
  • AMI ID for region ap-southeast-2: ami-97483dad
  • AMI ID for region ap-northeast-1: ami-0e08150f
  • AMI ID for region sa-east-1: ami-dd4ff2c0

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 mr3.7.1 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.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


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 mr3.7.1 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!
