Subject: Home Network With VoIP Performance Problem [7:104244]
Hello again, my friends. It has been a very long time.
I present for your consideration a problem I encountered a couple of
months
back when I moved my telephone service from POTS to VoIP via my
broadband
internet connection. Let me assure you I am not looking for
troubleshooting
help. The problem is long resolved. I thought you folks might just enjoy
the
troubleshooting exercise. See if you can derive the reason for the
problem
occurring, and the actions that ended the problem.
Please refer to the diagram found at
http://www.chuckslongroad.info/VoIP_Net.htm
I hope that the diagram is clear enough and describes all the components
accurately and provides all the pertinent information. I will check back
and
clarify where necessary.
Given the described topology, all computers in the network, both on the
wired and wireless side, have perfect access to the internet. All web
browsing, e-mail, etc works just fine.
When POTS phone XXX-XXX-XXX0 ( right side - wired - of the diagram ) is
off
hook ( in use ) all computers in the network have perfect access to the
internet.
However, when POTS phone XXX-XXX-XXX8 ( left side of the diagram ) is
off
hook, no computer has internet access. All phones work just fine. In
fact
when I was troubleshooting, I could speak on XXX0 with the various tech
support entities, whether XXX8 was on or off hook.
Another bizarre phenomenon was that when downloading large files (
dozens of
megabytes ) the download would proceed for a time and then stop. By
restarting the download several times, I might eventually get the entire
file. This phenomenon would occur only when XXX8 was on hook. As stated
earlier, if XXX8 was off hook, FTP did not work at all.
As I said, the problem was resolved long ago. I found the eventual
solution
quite interesting. I hope you enjoy the puzzle. I look forward to your
analyses.
Chuck
