Use Cases

Unable to show "metadata-from": No such page "_space_variables"
 supports the following use cases (based on SIPREC RFC 7866 and RFC 6341)

  • Recording Sessions for a single audio media stream towards a single SRS (NICE SIPREC Server).
  • Recording Sessions towards SRS for a basic call with priority given to the calling party side (ingress leg).
  • Recording Sessions for Call Hold and Retrieve.
  • Recording Sessions for Transferred calls.
  • For all the call related use cases mentioned above, the appropriate metadata XML and SDP information is relayed to the SRS as part of the RS.
  • Recording Encrypted RTP (SRTP) streams and sending related keys in the SDP towards the SRS as part of RS.
  • Only Proxy (non-transcoding) media towards the SRS is supported.
  • Only statically configured (non-dynamic) Recording Sessions are supported.
  • Recording Signaling group polls the SRS server using existing OPTIONS mechanism; if SRS is unreachable, the corresponding alarm will be generated.
  • Recording Signaling Group uses a subset of existing Signaling Group and SIP Server Table functionality to use listen ports, destination IP/FQDN, protocol and port etc., to communicate with the SRS.
  • SWe Edge rejects INVITE, OPTIONS requests originating from SRS Servers.
