Encryption Protocols
Microsoft Point-to-Point Encryption (MPPE) encrypts data in
PPTP VPN connections. MPPE provides privacy to a tunnel.
When you use MPPE and PPTP together, a VPN is created.
You can set the MPPE protocol on the Tunnel Modify web
page using the Encryption Algorithm field. From the CLI,
you set MPPE by specifying MSCHAPv1. See the CLI User
Guide for more information.
SIP Phone Support
Session Initiation Protocol (SIP) is an IP protocol that
supports a networked telephone that converges voice and
data on a single network. This instrument is a smart device
that performs many of the functions that are traditionally
handled by the phone company's central office equipment.
When you connect SIP and the OCR 812, the SIP phone is
registered with the proxy server supplied by your ISP. If you
want to use SIP and NAT, you must select the PAT option of
NAT. For more information, see the Remote 812 ADSL
Router Online User's Guide.
