  • December release for 2014 is 14.10
  • April release for 2015 is 15.04

Release Level History

  • 14.04 - April 30 2014
  • 14.04.1 - June 01 2014
  • 14.04.2 - July 11 2014

New Features


Release 14.04.4

  • UC-3438 - Create Proxy plugin to solve MoH / Ringing overlap for poorly behaving SBCs
    • The plugin will do the following: 1. Check if the sipfrag of a notify is a 180 Ringing. 2. Convert to sipfrag 100 Trying before sending to Polycom
    • End result: Polycom will only send BYE upon receipt of sipfrag 200 Ok. **The intention is to let MoH play the entire alerting phase.
    • In the old use case where call goes to a mobile phone, sipfrag will be 183 Session Progress. This will not be changed by the plugin. This would result to MoH stopping to avoid the media overlap.
    • This new feature is disabled by default, will affect only notifies for event refer and will not have any effect on routing, but would effect when Polycom tears down MoH.


Release 14.04.3

MongoDB Enhancements

  • XX-11389 - Two new check boxes have been added under System>Database Settings in openUC to allow administrators to set logging details for the Mongo C++ driver:
    • The Enable mongo driver logging check box determines whether the Mongo C++ driver is logged to the system logs.
    • The Mongo driver log level check box determines the log level used by the Mongo driver logger.
  • XX-11390 - A new option named Mongo query timeout has been added under System>Database to allow administrators to specify the query timeout used by SIP components mongo C++ driver. The default value is 500 milliseconds.
  • XX-11378 - The system has been enhanced to allow sipXecs components to merge contact results for new registrations and read data from the local MongoDB node. Also, the clusterId parameter is now included in the read preferences.
  • XX-11382 - The SEC functionality has significantly increased performance when administrators query the logs for alarms. This has been achieved because the system now writes all alarms related logs in a separate directory instead of writing them in the /var/log/sipxpbx directory. Note that SEC still uses a lot of CPU when sipxconfig.log is on DEBUG.


Release 14.04.2

There are no new features delivered in 14.04.2


Release 14.04.1

There are no new features delivered in 14.04.1


Release 14.04

  • User Portal ReWrite
    • This is essentially the new Web version of Unite in 'Lite' form (no XMPP capabilities).
    • The user will be able to manage their communications settings, listen to voicemail, see call logs, change their call forwarding, etc. Essentially what they can do in the User portal today in a nice new interface.
    • The old user portal is still available by disabling the new one (see System -> Admin Settings).
  • Auto Attendant Improvements - A number of improvements to our Auto Attendant
    • Live Attendant - A user or hunt group can be specified in AA configuration to ring during certain hours of the day.
    • Restricted Dialing - Allow only certain extensions to be dialed from an Auto Attendant.
    • Make Please Hold Optional - After a menu selection is made there is an audio prompt that says 'Please hold while I transfer your call'.This prompt is now optional.
    • Auto Attendant Night Mode - The ability to manually put an AA in or out of night mode.
    • Specify a Locale per AA - Be able to specify a locale (language) on an AA by AA basis.
    • Holiday Attendant Improvements - Be able to define holiday attendant day AND hours of operation.
  • Change Logging Levels on the fly
    • In previous version of openUC customers have been forced to change logging levels after hours because it required services to restart to pick up the changes.
  • Multi-User Chat Room Management
    • While openUC's Instant Messaging services have had the ability to have multi-user chat (MUC) rooms, they needed to be managed as just other users on the system.
    • With the new Multi-User Chat Room management it is now easier to configure these MUC's.
    • Additionally MUCs can now be limited to a group of users and message logging can be enabled/disabled on a MUC by MUC basis.
  • Login by email address - The ability for the system administrator to allow users to login with their email address (or email alias) and their system password / LDAP password / RADIUS password.

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 4 GB of RAM with sufficient swap space
  • 80 GB disk (75 users depending on usage patterns)

Note: sipXcom supports an unlimited number of voice-mail 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.An i386 version is also provided as is (without any support).


  • Phones
    • Polycom VVX Devices with firmware 4.1.6 or later are recommended for new installations
    • AudioCodes Gateways are recommended for PSTN connectivity
  • SBCs
    • Sangoma, AudioCodes, 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 sipXbridge - "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. It does not work in a HA setup nor does it scale particularly well.

Installation and Upgrade Notes

Installation note for 14.04.3

After sipXcom 14.04.3 is downloaded and installed,the clusterId read tag is unique (same as locationId). Follow these steps to propagate the new read tags to the MongoDB replica set:

  1. In the OpenUC menu, click System>Database.
  2. Click the Add query metadata button.
  3. To verify that the MongoDB replica contains the unique read tags, run in the command line:
mongo rs.config();

Special MongoDB note

Please be aware of this 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 64000mongodb hard nproc 64000mongodb soft nofile 64000mongodb hard nofile 64000 .

This note also applies to the 14.04.3 release.

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 sipXecs 4.4


  • We recommend to test in your lab all operations prior to upgrade
  • Please make a backup of your production servers
  • Please contact support when you are planning this upgrade
  • There are two known issues related to upgrade from sipXecs 4.4
    • Legacy OpenACD is not included in the builds anymore. sipXCallQueue is the new call queueing system
    • Polycom phones that were defined in SCS 4.2 were allowed to leave the field device_version_id blank. This field was also allowed to be blank in openUC 4.4 but in later versions this field cannot be null otherwise sipXconfig will not start.

More information and solutions to the above issues can be obtained by accessing our KnowledgeBase

Upgrade from sipXecs 4.4 is based on the following backup/restore procedure:

  • Create a backup of the current sipXecs 4.4 system
  • Install a fresh sipXcom 14.04 on a new machine. Finish the installation and configuration by running sipxecs-setup to obtain access to WebUI
  • Restore 4.4 configuration on the new sipXcom 14.04 system.


Upgrade from sipXcom 4.6

Upgrade from sipXcom 4.6 is based on the procedure:

  • Perform a backup of the entire system
  • Download backup from the server
  • Download and run new openuc-setup script using the following commands:
  • When prompted to update openUC, select yes. All necessary updates should be downloaded and installed.
  • Once the update is complete, reboot server with the reboot command


Special NOTE for sipXecs 4.6 Versions Older than Update 9

The pymongo package in our sipXecs repository is outdated and should be replaced with the differently named but newer version python-pymongopackage from the EPEL repository. This allows pymongo to upgrade along with other OS packages from the upstream provider (EPEL) rather than sipXcom repository.

  • Not all Updates previous to Update 8 have pymongo installed. If upon running yum update you encounter a message similar to:
Error: Package: pymongo-2.4.2-1.el6.x86_64 (@openuc)
Requires: python-bson = 2.4.2-1.el6
Removing: python-bson-2.4.2-1.el6.x86_64 (@openuc)
python-bson = 2.4.2-1.el6
Updated By: python-bson-2.5.2-3.el6.x86_64 (epel)
python-bson = 2.5.2-3.el6
Available: python-bson-2.1.1-1.el6.x86_64 (epel)
python-bson = 2.1.1-1.el6
You could try using --skip-broken to work around the problem

DO NOT run yum update --skip-broken to proceed!!!!

As mentioned, the pymongo package in our openUC repository is outdated and should be replaced with the differently named but newer version python-pymongo package from the EPEL repository. This allows pymongo to upgrade along with other OS packages from the upstream provider (EPEL) rather than sipXcom repository. To do so, run these commands:

rpm -e --nodeps pymongo
yum install python-pymongo -y
curl > /usr/bin/openuc-setup
chmod +x /usr/bin/openuc-setup
  • When prompted to update openUC, select yes. All necessary updates should be downloaded and installed.
  • Once the update is complete, reboot server with the reboot command

After rebooting the system:

  • Run service sipxecs status to check if all services started correctly after upgrade
  • Login to Admin GUI, click on System -> Servers, Select all servers and click Send Profiles button

Resolved Internally Reported Issues


Release 14.04.3

  • XX-11381- Fixed an issue with the C++ driver that caused the MongoDB to stop working for approximately 15 minutes when using the default TCP timeout. Now, a query with a limited timeout can be specified by the administrator and the executions are correctly performed, thus allowing users to place calls continuously.
  • XX-11398-Fixed several issues that caused the system to incorrectly manage memory allocations. This issue occurred because the sipXtackLibnetwork stacks leaked memory of the SdpBody and NameValuePairs types and the SipClientSendMsg destructor was not virtual. Now, sipXtackLibbehaves correctly and the SipClientSendMsg has been made virtual.
  • UC-3252- Fixed an issue that caused the OpenFire plugin to incorrectly manage memory allocations and generate out of memory java exceptions. This issue occured when a non-IM user was modified in the Administration Portal and when groups with thousands of users were updated.
  • XX-10950- Fixed an issue that caused slow performances when using the proxy and registrar plug-ins. This issue occurred because the proxy and registrar plug-ins were making separate queries to the MongoDB to retrieve required information. Now, queries are made only once for each call and the results are sent to all plug-ins.
  • XX-11399- FreeSwitch processes are now running with a normal priority. Previously, the FreeSwitch process was assigned a higher priority than the proxy and occasionally caused the proxy to have insufficient resources to process calls.
  • XX-11384- Fixed an issue that caused the garbage collector to stop working when processing a large number of transactions. This issue occurred because the garbage collector was only scheduled to function when the user-agent queue was empty. Now, the functionality continues to collect stale transactions even in a constant heavy traffic scenario.

Resolved Customer Reported Issues


Release 14.04.4

  • XX-11584 - Write race on the same TCP socket descriptor
    • Fixed an issue whereby the socket::send operations are not thread safe and there is the possibility of missing some TCP packets if two threads try to grab the same socket at the same time.
    • The race condition applies only to TCP and the involved functions are SipClient::isWritable() and SipClientWriteBuffer::writeMore() since they are run in distinct threads.
  • XX-11462 - Fix log rotate behavior where log file gets recreated every 5 seconds
    • Fixed in issue introduced in 14.04.3 where log file changes caused an over abundance of logging and log files to not get rotated properly, this can lead to disk space getting consumed rapidly.
  • XX-11551 - Implement expire grace period for registrations
    • Fixed an in with that appears in distributed highly available systems where slight delays in database replication would cause registrations to drop for a short period of time. A grace period for registrations has been implemented to account for any delays that may occur during replication.
  • XX-11399 Revert - Start FS process with normal priority
    • Reverted a fix introduced in 14.04.3. Freeswitch starts with higher priority than proxy, it was observed during load testing AAs that FS got a big slice of CPU and proxy didn't have enough resources to process calls. Load testing AAs with 30cps went just fine after starting FS with lower priority (that is with -np option).
    • In live environments with customers running certain virtualization technology, this change caused static in MoH and poor quality conference bridging.
