Kan man ikke bare sette en hub som er skjult under benken eller noe sånt, imellom modemet og bredbåndtelefoniboksen? Også koble seg til huben?

slik: Veggkontakt --> Modem --> hub; port 1: | hub; port 2: Bredbåndtelefoniboks | hub; port 3: maskinen som brukes til sniffing | hub; port 4: --> Switch; Port 1: Fra bredbåndstelefoniboks | Port 2: Datamaskin | Port 3: Datamaskin | Port 4: Datamaskin

Vil ikke det fungere?

Security

The majority of consumer VoIP solutions do not support encryption yet. As a result, it is relatively easy to eavesdrop on VoIP calls and even change their content. There are several open source solutions that facilitate sniffing of VoIP conversations. A modicum of security is afforded due to patented audio codecs that are not easily available for open source applications, however such security through obscurity has not proven effective in the long run in other fields. Some vendors also use compression to make eavesdropping more difficult. However, real security requires encryption and cryptographic authentication which are not widely available at a consumer level[4]. The existing secure standard SRTP is available on Analog Telephone Adapters(ATAs) from some manufacturers like Sipura/Linksys, with a certificate from Voxilla, a VoIP information site. SRTP is also available for Gizmo Project for softphones (PCs/laptops emulating a phone).

The Voice VPN solution provides secure voice for enterprise VoIP networks by applying IPSec encryption to the digitized voice stream.
