Dynamic DNS (dynDNS)
Enables the registration of IP addresses with a dynDNS provider in the case that fixed IP addresses are not used for the VPN connection
Specific DNS forwarding
DNS forwarding according to DNS domain, e.g. internal names are translated by proprietary DNS servers in the VPN; external
names are translated by Internet DNS servers
names are translated by Internet DNS servers
VPN throughput (max.)*
1364 byte paket size
11,5 Mbps
265 byte paket size
4,5 Mbps
Hint
* by AES encryption and active VPN hardware acceleration
Firewall throughput (max.)
1470 Byte paket size

VoIP (optional)
Extended VoIP support (only with LANCOM VoIP Options)
SIP proxy
Management of local SIP users with optional automatic registration/authentication. Mapping of public SIP provider accounts
as telephone lines for shared use. Connection to up to four upstream SIP PBXs including line backup. SIP connections from/to
internal subscribers, SIP provider and SIP PBXs with automatic registration of SIP users at SIP provider/upstream SIP PBXs.
Optional shared/individual password for authentication at an upstream SIP PBX. Automatic
bandwidth management and automatic configuration of the firewall for SIP connections. Default DNS entry for the local SIP
domains, support of service location (SRV).

SIP/ISDN gateway
Operation direct at ISDN exchange lines or at ISDN extension lines of existing PBXs. Local ISDN subscribers register as local
SIP users, and local ISDN subscribers automatically register as SIP users at upstream SIP PBXs/SIP Providers. Number
translation between internal numbers and MSN/DDI and automatic adaptation of caller numbers and called numbers at the transition.

SIP trunking
By using SIP trunking (ITU Q.1912), an appropriate SIP account can be used by multiple subscribers, each of which has an
individual extension number.
individual extension number.
SIP remote gateway
Dial-in or dial-out from/to the local telephone network at a remote site with number translation made available for a central
SIP PBX/SIP provider
SIP PBX/SIP provider
Call router
Central switching of all incoming and outgoing calls. Number translation by mapping, numeral replacement and number
supplementation. Configuration of line and route selection, entry of multiple alternative routes (line backup). Routing based
on calling and called number, SIP domain and line. Manual routing by the user ("outside-line access codes"); routing with line
selection keys on telephones or telephone number prefixes; targeted routing for individual telephone numbers (e.g. emergency
calls via local ISDN); separate routes for internal, local, long-distance or international calls; blocking of telephone numbers or
blocks of telephone numbers; inclusion of local SIP or ISDN subscribers into the number range of an upstream SIP PBX;
internal standard telephone number for undeliverable calls; supplement/removal of line-related prefixes or trunk numbers

Signalling
VoIP: SIPv2, ISDN: DSS1 (Euro ISDN), 1TR6 (only at an external ISDN connection in TE mode)
Media protocols
RTP
Voice processing
Echo cancellation (G.168), automatic adaptive de-jitter buffer, inband tone signaling to the German standard. Transparent
pass-through for negotiated codecs, e.g. fax messages in T.38. Interaction on codec negotiation between subscribers
(filtering, optimization for quality or bandwidth). Voice encoding with G.711 µ-law/A-law (64 kbps), G.726(16, 24, 32, 40 kbps)

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
