| Note: You should never connect an unprotected computer |
|
|
| |
|
|
| directly with the Internet. Be sure to use an appropriate |
|
|
| |
|
|
| router for the Internet connection with an integrated Fire- |
|
|
| wall function. When you use SIP lines with the Aastra 800 |
|
|
| communications system, the router product used must be |
|
|
| compatible with the SIP protocol and the related RTP con- |
|
|
| nections. |
Tip: | To increase system security with a deactivated personal Fire- | ||
|
|
| wall you can restrict the protocol connections of the LAN con- |
|
|
| nection. Deactivate all elements not in use in the Properties |
|
|
| dialog of the LAN connection. The Aastra 800 communica- |
|
|
| tions system only requires the Internet Protocol (TCP/IP) |
|
|
| element. |
