[Asterisk-Users] small qos switch

Hi,

The lan is probably not the problem, but the dsl connection is.
There are some things you can do that can help to a certain degree.
First, set "tos=lowdelay" in your iax.conf.
Most routers obey the ToS field.
second, try to find out if your firewall (I assume you use one)
support QoS.
then there is a possibility you can set a QoS or ToS in the rulebase.
Maybe you can even set a guaranteed and maximum bandwidth for this
rule
(at least this is the way I work, but then again I use
Juniper/Netscreen firewalls)
The third choice is to use a switch that can set port based QoS or
ToS,
but make sure it is not reset? further down the line.

But having said that, if your provider does'nt do anything with QoS
and/or ToS it might al be useless.
Try and find out.

Regards

Andre

ONDERWERP:?[Asterisk-Users] small qos switch

I have multiple locations running * where all the phone are
on their own lan and all the data is on a separate lan.
The problem is they are sharing the same dsl connection.
The locations are IAX2 trunked together, but it only takes
one data down/up load to just kill the voice.

What I am looking for is a small switch with QoS that I
can stick in ahead of the dsl modem.  Plug in one connection
from the voice lan and one from the data lan.

I have found quite a few 24 or 48 port switches that will do
this, but I really do not need anything that big.  There are
already switches in place.

Any recommendations please?

thanks, bk...
