+1. Overview
- Using this module you can create independent
- applications/scripts to publish not sip-related information
- (e.g., system resources like CPU-usage, memory, number of
- active subscribers ...). Also, this module allows non-SIP
- speaking applications to subscribe presence information kept in
- a SIP presence server.
