reference: wikipedia on VOIP:
|
|
|
|
"Communication on the IP network is
|
|
perceived as less reliable in contrast to the circuit-switched public
|
|
telephone network because it does not provide a network-based mechanism
|
|
to ensure that data packets are not lost, and are delivered in
|
|
sequential order. It is a best-effort network without fundamental
|
|
Quality of Service (QoS) guarantees. Voice, and all other data, travels
|
|
in packets over IP networks with fixed maximum capacity. This system may
|
|
be more prone to data loss in the presence of congestion[a] than
|
|
traditional circuit switched systems; a circuit switched system of
|
|
insufficient capacity will refuse new connections while carrying the
|
|
remainder without impairment, while the quality of real-time data such
|
|
as telephone conversations on packet-switched networks degrades
|
|
dramatically.[16] Therefore, VoIP implementations may face problems with
|
|
latency, packet loss, and jitter.[16][17]"

Based on my own experience
|
|
|
|
I've seen VOIP have occasional dropouts.
|
|
I've seen copper be bombproof.
|
|
|
|
When copper was laid, it was done with care,
|
|
and it was built to last. VOIP is tacked onto internet connections as an
|
|
afterthought. It can work, but it can certainly not work. Where
|
|
on the other hand, copper will always work. Even if the power or internet
|
|
goes down.
|
|
|
|
Verdict: VOIP or Copper is ok, but copper will always be more reliable.
