Self-Service and Schedule call mode

Self-Service mode

This mode describes the usage model where users dial into their Spaces and VQCM is working in a reactive mode; as the Participants dial into the Space, a call on the Space is dynamically created by CMS and VQCM detects the new Call coming into existence via events posted by CMS to VQCM.

This is the mode that allows the greatest call volumes; customers have systems deployed hosting over a million call participants per month (1.1 and 1.3 million; 50k/70k call participants per day respectively).

On systems hosting large numbers of calls per month in Self-Service mode, we advise changing the ‘CallAgeing’ setting in the System Configuration database (see “VQ Conference Manager Configuration Options” document available from our Customer Portal - vqcomms.com/login) to a value of 1 (one) from its default of 40.

The CallAgeing setting controls when Calls are deleted once the call has completed; setting the value to one results in completed calls being deleted 24 hours after completion rather than 40 days later. On large systems, substantial numbers of Calls are generated which results in two things:

  1. Over 40 days, the system becomes slower and less responsive because it can have tens of thousands of Calls that it is repeatedly needing to scan and loop through
  2. If the system restarts, it can take the system minutes to initialize on account of the large number of calls. This can result in 504 Errors being displayed on the User Interface because the Core VQ service is unresponsive (it’s still initializing)

Schedule Call mode

This mode describes the usage model where Meetings are scheduled via the “Meetings List” or the “Schedule New MeetingcoApp.

Systems in this usage mode will typically be limited to less than 250 scheduled calls per day or 2500 per month.

In Scheduled Call mode, you might want to consider enabling “Call Ending“ messaging where VQCM will display "The call is about to end” messages into the video stream of each video participant when the call reaches 10 minutes before its scheduled completion time. The Message repeats at 5 minutes and then every minute to call end time. The message content and intervals can be configured.
