SIP Feature Server 8.1.2 known issues and recommendations
This document includes SIP Feature Server issues and recommendations applicable to the legacy 8.1.2 release.
Important upgrade step
If you are upgrading from a restricted release of SIP Feature Server 8.1.2 (any version prior to 8.1.200.83), you must manually restore the vms_host parameter, as follows:
- Open launcher.xml.
- In the vms_host section, in the line <format type="string" default="localhost" />, replace "localhost" with "0.0.0.0" or a specific IP address to restrict Feature Server web application access to that address.
If you are doing a fresh installation or upgrading from 8.1.200.83 or later, you can omit this step.
Feature Server upgrade requires manual Cassandra file backup and restoration
Before you upgrade Feature Server, you must first back up your Cassandra configuration and database files, then restore them after the upgrade. Complete these steps:
- On the Feature Server master node (which is also the Cassandra seeds node), back up all files in the etc folder, which includes the cassandra.yaml file.
- Back up the database files for all nodes in the Cassandra cluster (because the upgrade propagates changes to all nodes in the cluster). Note the file locations.
- After completing the Feature Server upgrade, restore the backed up configuration and database files to their original locations.
- Restart Feature Server and use the Feature Server administrative web application to verify that it is running.
- Repeat these steps on each node.

When the network is disabled on the host on which Feature Server is running, Windows may terminate unexpectedly
