Hi Rohan,<br>
<br>
I have a similar setup to you and don't have too many problems with
VOIP at all.<br>
<br>
Sipura SPA3102 on Pennytel<br>
G711A codec used<br>
6 Households with 11+ computers and 1 web/mail server<br>
ADSL1 8 Megs down 384 K up<br>
3 hops of wireless and 25 Km between me and the DSL<br>
Shared with melbourne wireless traffic on some of the links<br>
We limit bandwidth to 90% of max in each direction<br>
<br>
The difference....<br>
<br>
We have a linux router running Centos 4 and use HTB to control
bandwidth and do exactly what you are considering, allocating minimum
bandwidth on a per IP address basis. We use a shell script to set the
whole thing up. You can get it from here <a

. It may not be exactly what you want but you may well get some ideas.<br>

<p>hello everybody,<br>
<br>
i've decided to give my voip QoS another shot; atm its currently
working*, though its far from perfect and i think there's potential of
getting it much better.<br>
<br>
currently im using an alcatel 510 (alcatel-home firmware upgraded, with
sip port opened) connected to an asus wl-500gp with tomato v1.17
firmware and shared with 7 people, both wired and non-wired.<br>
i also have attached a wired sipura 3102 ATA.<br>
<br>
im with tpg adsl2 internet and i sync at 7mbps-down/.9mbps-up. i've
capped my speeds to 5.6mbps-down/724kbps-up respectively (or 80% of
each).<br>
i use pennytel as my vsp. <br>
<br>
i make calls through my wired connection to the router and also through
my ata. on my ata i use the g729 codec and on my pc i use g711.<br>
<br>
atm i'm using l7, port classification and mac prioritisation (for the
ata) in my QoS setup. please see <a moz-do-not-send="true"

border="0" height="6" vspace="2" width="6"></a> for details<br>
<br>
in terms of the problem itself, i think its probably packet loss- as
the other end seems to complain of 'drop-outs' or that they can't hear
me sometimes. echo is a peripheral issue but still worthy of mention,
as some people don't like it.<br>
<br>
what irritates me most is that, though i seldom max-out (particularly
when i call out- i monitor it!) my connection, my voip calls still seem
to get disturbed by other traffic on the router, even when the router
has no other concurrent traffic (which voids the idea that greater
bandwidth alleviates quality issues). <br>
<br>
seeing as i have a bandwidth surplus, is it possible to permanently
allocate bandwidth to voip services- have bandwidth exclusively set
aside and untouchable by other services?<br>
<br>
any insights appreciated !<br>
<br>
thank you<br>
<br>
