Active forwarding to local users

  1. An external user A makes a call to an internal user B (SIP, ISDN or analog).
  2. B makes a further call to local user C. These two users can reach each other directly, so the LANCOM VoIP router only handles the signaling by means of SIP; the data transfer via RTP takes the shortest possible route.
  3. Local user B initiates the call forwarding (attended/with flash) to C.
  4. The LANCOM VoIP router manages the call forwarding.




Note: In case of SIP at the external subscriber, this requires that Transfer in SIP (re-invites) is fully supported.
