LANCOM 1823 VoIP
Analog modes Operation directly at an analog exchange line (DTMF) with the combined FXO port. Internal FXS ports (DTMF) for each
single analog terminal device or as analog exchange lines for an analog PBX.
Audio processing Echo cancellation (G.168), automatic adaptive de-jitter buffer, inband tone signaling to EU standard and country specific.
DTMF support according to RFC 2976 (SIP info) or RFC 2833 (RTP payload type/outband). Transparent pass-through for
negotiated codecs. Interaction on codec negotiation between subscribers (filtering, optimization for quality or bandwidth).
Voice encoding with G.711 ยต-law/A-law (64 kbps), G.726 (16, 24, 32, 40 kbps), G.722 high quality codec, G.729 annex A
Auto QoS Automatic dynamic bandwidth reservation per SIP connection. Automatic selection of compression method depending upon
available bandwidth. Voice packet prioritization (CoS), DiffServ marking, traffic shaping (incoming/outgoing) and packet-
size management of non-prioritized connections compared to VoIP
VoIP management VoIP Setup Wizard in LANconfig; status display of subscribers, lines, and connections; logging of VoIP Call Manager events
in LANmonitor. SYSLOG and TRACE for voice connections
