SIP intercoms send regular keepalive messages to the Sipelia™ Server to indicate that they are still running and connected. The Sipelia™ Server knows how often to expect a keepalive message based on the registration timeout which is sent from each SIP intercom. You can configure a device registration margin as a safeguard for SIP intercoms that might exceed their registration timeout period.
Before you begin
- Create a backup of the following file:
- Investigate the registration timeout for the SIP intercoms in the system. Depending on the devices you have connected, this setting might be configurable or hardcoded.
What you should know
- SIP intercoms can sometimes send their keepalive message shortly after their registration timeout period has elapsed. When this happens, Security Center reports that the device is fluctuating between online and offline states. This issue can be solved by increasing the device registration margin which adds additional time to the device's registration timeout period.
- The default value of the device registration margin is 60 seconds. The minimum accepted value is 0 seconds.
- Deactivate the Sipelia™ plugin role
Open the following configuration file:
- To adjust the device registration margin, locate the DeviceRegistrationMargin element and modify the value (in seconds).
- Save the file and reactivate the Sipelia™ plugin role.
