[asterisk-users] Call quality

[Loic Didelot]

Hello,
one of my customers complained about bad voice quality on several calls,
so I programmed a button on each phone which users can hit if they have
audio drops and echo.

I did this to check if there is a common recurrent problem to a given
destination or just for one user etc... But till now I could not detect
a pattern which could explain the problems

This "alert button" is pressed between 7%-10% of all calls. The customer
has 25 phones and around 300 calls per day.

The SNOM phones are connected to Linksys switches and are totaly split
from the computers network. The same goes for the asterisk box. No calls
are routed trough the internet.
Phone -> Local Lan -> Asterisk -> Zaptel (Junghanns BRI card) -> Carrier

The carrier we use is known for his good quality and we never had a
problem. It is the historic and most expensive carrier in Luxembourg.

Asterisk is running on a 1GHZ VIA CPU with 1GB RAM box. They have a
maximum of 6 concurrent calls.

Maybe someone can help me to track down the problem. What should I
check, monitor test. Any ideas are welcome.


Best regards,
Loic Didelot.
