CallVoip biedt een veel ruimere dienstverlening en garandeert bovendien dat alle huidige ISDN-nummers overgenomen kunnen worden. Ook is het met behulp van een zogeheten Fritz!Box 7270 mogelijk bestaande ISDN-apparatuur aan te sluiten. De Fritz!Box is een router, mini-telefooncentrale, DECT-basisstation en draadloos toegangspunt (WiFi) in een.
Kies voor de FRITZ!Box 7170 of FRITZ!Box 7270 en u kunt uw ISDN-apparatuur gewoon blijven gebruiken, zonder dat u nog de ISDN-dienst afneemt. De FRITZ! praat ISDN met uw apparatuur, en u belt voordelig via VoIP uit.

If you have a Vyatta build environment setup, you can configure the build using "./configure --with-xensourcevm" and it will produce an image file that is compatible with XenSource. The actual steps that are taken can be viewed in the livecd/mk.livecd.functions file. Take a look at the vyatta-xensource-partition-image() function.

De voor opname in de .nl-zonefile opgegeven name servers dienen vanaf het hele internet bereikbaar te zijn via UDP-poort 53, en ook via TCP-poort 53. Wanneer de domeinnaam responses op queries genereert die groter zijn dan 512 octets dient bovendien het EDNS0-protocol (RFC 2671) ondersteund te worden.

The traffic engineering term quality of service (QoS) refers to resource reservation control mechanisms: the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. In the absence of network congestion, QoS mechanisms are not required.

|---|---|
| Layer-5 / Application | HTTP-Proxy |
| Layer-4 / Transport | SOCKS |
| Layer-4 / Transport | Transparant Proxy |
| Layer-3 / Network | NAT |
GRE tunnels are designed to be completely stateless.
The GRE Tunnel IP MTU is set to 24 bytes less than the physical interface MTU by default.

NOTE: - ntpdate will update the clock at once after consulting the time source BUT: it will not skew/slew and that can upset running programs SO: only run it at startup - ntpd will update the clock in small steps and keep it synchronised BUT: it will panic exit when encountered with more the 1000s difference SO: when ntpd is not running, run ntpdate and restart: ntpd
