Authentication section:
The PPP protocol allows reciprocal authentication (inbound/outbound). Generally
speaking, for inbound connections, only the
inbound authentication is required,
for outbound connections, only the outbound authentication. But it can also
happen that an authentication is required both from the client and from the ser-
ver.
PPPOE section:
Here, the interface can be configured as a PPPoE client (for example, for DSL).
PPTP section:
This operating mode applies for inbound and outbound calls. The PPTP (Point-
to-
P oint T unneling P rotocol) implements private VPN connections via the Inter-
No IP Hea-
der Com-
pression The VoIP devices support the compression of voice data
along the PPP link using the
RTP header compression
method (RFC 2508, 2509). This drastically reduces the requi-
red bandwidth for VoIP calls. To suppress this, the
No IP
Header compression check box must be enabled.
