Fixed issues

IDDescriptionVersions affected
168955681When installing IVG on two or more servers with local PostgreSQL, the same IP address was listed for all servers in the CTI Event Consumer configuration file (hvp_params_ctieventconsumer.cfg). Now, each server is assigned its own IP address.3.10

Call Control Interaction Server (CCIS) did not wait for confirmation that all interaction data, such as UCID, had been updated before creating an outbound session. This could cause outbound calls to fail and new holding calls to be created unexpectedly.

Now, CCIS waits until the UCID has been updated before creating an outbound session.

3.1 - 3.11
168187410

The IVG installer did not check for the "noexec" permission in /etc/fstab for the tmpfs file system. If present, "noexec" caused the Holly Patch Installer to fail. The installer also did not check to ensure 4GB of storage space were allocated.

The installer now checks these items and will mount the file system with the required configuration if needed.

For RHEL and CentOS 6.10:

  • If tmpfs is already mounted with incorrect configuration, the installer will mount the file system as the last entry in /etc/fstab.

For RHEL and CentOS 7.7:

  • If tmpfs is already mounted with incorrect configuration, the installer will mount the file system as the first entry in /etc/fstab.
Prior to 3.11
