Chapter8. SIP Services
Note:If more than one Messenger client performs file transfer through the Telecommuting Module at the same
time,they could end up sending to each other’s peers instead of their own. An attacker could possibly use this to
intercepttransfered files; don’t use this mechanism to transfer sensistive data.
Here,you select to turn Open port 6891 On or Off. Recommended setting is Off.
Allow RFC 2069 authentication
SomeSIP units can’t handle Digest authentication as described in RFC 2617, but they still do authentication. 3Com
VCXIP Telecommuting Module can allow the simpler form of authentication described in RFC 2069 to be able to
interoperatewith these units.
Toallow this can decrease security. Use it only if units in your system need it.
Selectif authentication according to RFC 2069 should be allowed (On) or not (Off). It is recommended to keep this
settingoff.
