eZuce is pleased to announce the General Availability of sipXcom 19.04.

There are again two releases for sipXcom 19.04, one for CentOS 6 and one for CentOS 7. The documentation around Installations and Downloads is being updated now with CentOS 7 as the recommended OS moving forward. We’ll also update the video to cover CentOS 7 Minimal installation. While this is a relatively small update, there are a few interesting things to point out.

When a user is deleted from the system, the configuration services will now go through all phones and remove that user from the phones and re-send phone profiles. If that was the only user on the phone, the phone will go back to the auto-provision ID. What we were finding is that administrators were deleting users but not re-sending phone profiles. This would result in traffic floods of SIP traffic with bad subscribes to MWI and invalid registrations to the server.

The new Polycom VVX ‘50’ series phones are now supported for configuration as well as auto-provisioning. Firmware versions 5.9.0 and later are supported.

Also, mongoDB has been updated to 3.6.11. This has had a positive effect in recovery from a node outage. The new mongodb seems much more resilient.

Please note that this will be the last release for CentOS 6. As of version 19.08 we will only be releasing sipXcom for CentOS 7! To go from a CentOS 6 based system to a CentOS 7 based system will require a backup and restore to a fresh CentOS 7 installation. As such a parallel install will be recommended.

We’ve also decided to put the container (Docker) work on hold for now. There were complexities around networking and implementation that we didn’t feel warranted the effort involved to work past them. Additionally, there wasn’t significant customer demand to warrant the effort at this point. We’re pushing ahead with some newer features instead.

  • Support for Polycom VVX 150, 250, 350 and 450
