eZuce is pleased to announce the Beta Release of Uniteme 19.04.

As a beta release, some of these notes may be revised before the actual release.

Important - For Beta Testers - Do not directly upgrade to 19.04 from any version before 18.04. The 18.04 upgrade must be completed first. Please read the release notes for 18.04 if you are not on 18.04 yet.

There again will be 2 releases for 19.04. A CentOS 7 release (19.04.centos7) will follow shortly. While it’s a 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 which would then create traffic floods with bad subscribes to MWI and such to the server.

The new Polycom VVX ‘50’ series phones is now supported for configuration as well as auto provision! Firmware 3.8.0 and later supported.

Also, mongoDB has been updated to 3.6.9. This has had a positive effect in recovery from a node outage. The new mongodb seems much more resilient.

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


uniteme New Features:

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

  • Alarm for Certificate Expiration

  • Make mongoDB cache size configurable

  • Remove user from phones automatically after user deleted from system

  • Automatically generate certificate from Let’s Encrypt.

uniteme Improvements:

  • Sort alarms alphabetically

  • Upgrade mongodb to 3.6.9

  • Add http provisioning option to DHCP configuration


  1. Full Beta Release Notes with installation information are located here: 18.12 Full Beta Release Notes

  2. The regular release of 19.04 will have the ability to upgrade from earlier versions using the upgrade script used in 18.04. For the purposes of this beta release, please only do upgrades from 18.04 if you test systems are on a version earlier than 18.04, upgrade to 18.04 first.

Who Should Install?

This is a beta release and not recommended for production use.

This release is recommended for all 4.6 and later installations. If you have a patch installed to your system a new patch may be required. Please contact if think you may have a patch applied as that may be replaced during the update.

eZuce's software products continuously progress through an Agile based development methodology that keeps feature functionality comprehensive and up-to-date in response to evolving market and customer requirements.

New software releases are made at a rate of two to four releases a year. Releases are numbered in the <yy>.<mm>.<uu> format where <yy> and <mm> designate the year and the month, respectively, in which a release is made generally available. Where applicable, <uu> corresponds to an update release relative to a general release on which fixes are made available.

In order to ensure service continuity and stability, customers may keep their production environments unchanged for up to a 6-month period during which release updates or patches are made available. After a release is more than 6-months old, eZuce customers would have to upgrade to the latest generally available release - inclusive of all fixes to date and any new patches.


If you have questions about updating you can email or if you need assistance with the update contact your account manager or email

System Requirements

For a reasonably performing system, we recommend the following configuration.

Minimum hardware requirements

  • Pentium 4 or Xeon processor @ 2.0 GHz Core 64bit or higher
  • Minimum 8 GB of RAM with sufficient swap space
  • 80 GB disk (75 users depending on usage patterns)


  • uniteme supports an unlimited number of voicemail boxes, the total number of hours of recorded messages is determined by the size of the hard-disk. As a rule, for every minute of recorded messages, you will need 1 MB of disk space (About 3 hours per 10 GB of disk space).

Operating System

CentOS/RHEL 6 x86_64 with latest updates is required.



  • Polycom VVX Devices with firmware 5.9.1 (split) are recommended for new installations
  • Polycom SoundPoint IP Devices should run firmware 4.0.14 (split)


  • AudioCodes Gateways are recommended for PSTN connectivity


  • Frafos, Sangoma, Acme Packet and Ingate SBC's are recommended for SIP Trunking and Remote Worker connectivity (commonly referred to as sipXbridge and MediaRelay services respectively).
  • NOTE: The eZuce uniteme - "Use built-in SIP Trunk SBC" found in Gateway Details for use with Trunking or Remote Worker solutions should be used only for lab purposes. Additionally, sipXbridge does not work in an HA environment.

Installation and Upgrade Notes

Special MongoDB note

Please be aware of these Mongodb requirements Note: Both the “hard” and the “soft” ulimit affect MongoDB’s performance. The “hard” ulimit refers to the maximum number of processes that a user can have active at any time. This is the ceiling: no non-root process can increase the “hard” ulimit. In contrast, the “soft” ulimit is the limit that is actually enforced for a session or process, but any process can increase it up to “hard” ulimit maximum.Every deployment may have unique requirements and settings; however, the following thresholds and settings are particularly important for mongod and mongos deployments:

ulimit –a
-f (file size): unlimited
-t (cpu time): unlimited
-v (virtual memory): unlimited
-n (open files): 64000
-m (memory size): unlimited
-u (processes/threads): 32000


Always remember to restart your mongod and mongos instances after changing the ulimit settings to make sure that the settings change takes effect.If you limit virtual or resident memory size on a system running MongoDB the operating system will refuse to honor additional allocation requests. After every install/upgrade please check that "cat /proc/$pid_of_mongo/limits" have the recommended value of 655350. To make this value permanent you need to create this file /etc/security/limits.d/99-mongodb-nproc.conf and add the following lines:

mongodb soft nproc 64000
mongodb hard nproc 64000
mongodb soft nofile 64000
mongodb hard nofile 64000

Special Patch Note

If you have a patch installed to your system a new patch may be required. Please contact if think you may have a patch applied as that may be replaced during the update.

Upgrade from previous versions

New Procedure

We will be utilizing an upgrade script to ensure upgrades proceed as intended and so that customers have the appropriate warnings and information before upgrading.


Make sure you backup your system (configuration and voicemail at a minimum) prior to installation. You'll be upgrading mongodb to a new version!

Upgrade to 18.12 for Single Server systems for 17.10 and Older

Backup your System

Login to the Admin GUI and click on System -> Backup and at a minimum backup configuration and voicemail.

Do it now... before you go any further.


Login to the primary server as root.

Execute the following:

wget https://'USERNAME:PASSWORD'
chmod +x


Execute the upgrade script and answer 'Yes' to continue:



The following will be displayed:

Uniteme 18.12 Upgrade Script
IMPORTANT: If this is a multi-server cluster, all databases except the Primary (which must be on the configuration server) should be removed.
IMPORTANT: You should run a system backup and copy your config and voicemail backups to another system. If the upgrade fails, you will need to build a new server and restore from backup.
IMPORTANT: Ensure that you have enough disk space available for a copy of the Mongo databases. (roughly your Config + Voicemail backups).
IMPORTANT: 18.08 does not have Reachme in it, if you use Reachme on this server or in the cluster, do not continue!
This script will do the following:
- Back up mongo config and dbs
- Stop mongo instance and remove old mongo files
- Change 17.10 occurrences in /etc/yum.repos.d with 18.12
- Perform yum update and then reboot the machine
On sipxconfig service startup following steps are taken (in case there is a backup still on the disk):
- Restore mongo config and dbs, then remove from disk
- Reboot machine
For other cluster servers:
- Run same script
- Re-add databases that were removed.
Continue? (you must enter Yes or No as shown and press Enter):

Enter 'Yes' and press Enter to continue. The system will reboot a couple of times as part of the process.

Upgrade to 18.12 for Multi-Server Clusters with Multiple Database Servers for 17.10 and Older

Backup your System

Login to the Admin GUI and click on System -> Backup and at a minimum backup configuration and voicemail.

Do it now... before you go any further.

Remove All Secondary Databases from Cluster Nodes

From the Admin UI remove databases from all nodes except for the primary node. Click on System -> Databases do accomplish this.

Proceed as with Single Server for Primary

Proceed as above with the 'Download' section and then the 'Run' section.

Secondary Servers in Cluster

After the Primary Server has completed, repeat for each of the Secondary Servers in the cluster until all are completed. 

Add Database Nodes

After the secondary nodes are complete and done with their reboots, log in to the Admin UI and add back the database nodes that were removed.

Send Server Profiles

Login to web interface as superadmin.

Navigate to System -> Servers page. Place checkmark next to server names and click 'Send Profiles'.

SEC Service Upgrade Note

When upgrading uniteme from openUC 4.6 Update 11 or 14.4.3 to 15.06 follow these steps to ensure the SEC service is correctly running:

  • 1. Upgrade from 4.6 Update 11 or 14.4.3 to 15.06.
  • 2. After the upgrade is complete, perform the usual restart.
  • 3. Once possible, connect via CLI and monitor processes using top. Notice that the SEC process is using a lot of CPU memory.
  • 4. Perform another restart OR restart only the Sipxlogwatcher service.

Modified Files Upgrade Note

If you have manually modified any system related files or some files are not as yum would expect them to be, the yum update process may not overwrite them. It will instead create 'rpmnew' or 'rpmsave' files and not overwrite the files. The administrator may have previously modified the files knowingly or as part of a patch supplied by TAC.

To check your upgrade.log and search for *.rpmnew *.rpmsave on your system check the upgrade log:

You will be responsible for merging any changes from the old file to the new or contacting Technical Support if you require assistance.
