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... -- Bob Knight [-w] the work option bk@minusw.com 925-449-9163

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.

I run it on a Soekris Engineering embedded PC just for convenience, though there is a release for plain vanilla PCs with dual NICs. The PC version can boot from CD and store its configs on floppy or USB key.

Plug in one connection > > from the voice lan and one from the data lan. > Linksys WRT54G supports QoS, 4 LAN ports and a WAN port that can do DSL/cableIf you run Openwrt (www.openwrt.org) on this box you even can get IPSec VPN with X509V3 Certificates and a QoS that is really working - all that on CPE below 100USD. The following story from on of our customers homeoffices: DSL-Connection with 1Mbit/s Downstream and 128kbit/s Upstream. WRT54g with Openwrt as Router/VPN-Gateway. The user has a Snom 190 phone. Application is mostly terminal server with Citrx metaframe. Complaint from the user: every time I am on the phone my Citrix-sessions is _so_ slow... (1280x1024 Desktop in Highcolor). Solution of the problem: the phone was set to use G711u codec - and that did not fit together with the 128kbit/s upstream of the DSL-Line. But no problem with voice quality at all. QoS configuration slightly adjusted from the things you find at www.lartc.org . regards Torsten> > hth > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users > >-- Media Online Internet Services & Marketing GmbH Torsten Krueger torsten@nrw-online.de fon: 49-231-5575100 fax: 49-231-55751098 Kurze Str. 10 D-44137 Dortmund
I heard a great solution at Linux World Boston. A rather talented young man mentioned using a IPV6 VPN on the IPV4 internet. IPV6 supports QOS by default. Just VPN straight back to the CO and have your POP there so you only need one firewall too.

While your IPv6 encapsulated VPN would have QOS, the underlying transport medium (IPv4) still would not (if it didn't have it before). Furthermore, if any Ipv4 hops in between would have prioritized your traffic higher based on its type, they now have no idea what is is, because it's encapsulated. Daryl
I used Sveasoft but later shifted to OpenWrt for it's openness and flexibility. Check this at http://openwrt.org/OpenWrtDocs/About?action=show&redirect=OpenWrt I find this much more flexible as the underlying framework of the code building is same as Asterisk - Open Platform with many hooks possible.
