Has anyone figured this out yet? Lots of places say to add the following to sip.conf of an Asterisk 1.2 system (current production machine/Asterisk as root): tos=0xB8 (Hex B8 = Decimal 184 = Binary 10111000) or if you are running Asterisk v1.4 or newer: tos_sip=cs3 ; Sets TOS for SIP packets. tos_audio=ef ; Sets TOS for RTP audio packets. tos_video=af41 ;

Hi fellow traffic-shapers, I am implementing a Diffserv CORE router using Linux kernel 2.4.18. I used this excellent website (http://www.opalsoft.net/qos/DS-38.htm) using AFHTB as a starting basis for my EGRESS diffserv implementation - and all works great so far!!! But my project has an additional requirement. There are services running locally on the router which are sending/receiving IP

Hello list, I need to set Voice QoS and SIP QoS for YeaLink. The possible values are 0 ~ 63. With Grandstream I can fill in DiffServ 46, which is EF. That's what I want. With Snom I fill in 184, which corresponds to EF or DSCP 46 (according to their wiki) But what value do I want to fill in with this YeaLink ??? This is a conversion table :

I am trying to compare the behaviour of the Linux DiffServ implementation with that of Cisco, in DSCP remarking for traffic policing. As I understand it, the DSCP is marked at the egress interface (parent queue), based on the class that packets are in. I am looking at what happens at an inter-AS boundary. DSCP marked traffic coming into the Edge Router need to be policed and remarked: e.g. EF

Hi there LARTC, We are running a set of three systems for semiconductor technology, and would like to finalize our work in getting them to interoperate properly, but have run into some issues that touch on the very fabric of TCP/IP expertise. Iptables has already been used to solve "part of this", can we somehow use Diffserv capabilities to acheive the aims of modfiying packets such

Hello, all. I've stumbled across what seems to be a traffic prioritization issue in a Linux environment and wonder if anyone else has encountered or addressed this issue. We had planned to use expedited forwarding for our RTP and perhaps our SIP packets. Our plan was to set DSCP to 101110 (by the way, I think document http://www.voip-info.org/wiki/view/snom+360 is in error as I'm almost

Hello everybody, I have tried several iptables versions (from 1.2.4 to 1.2.6a) to mark outgoing packets (change the DSCP field) with no success. #iptables -A OUTPUT -t mangle -d 10.0.0.3 -j DSCP --set-dscp 0x2 iptables v1.2.6a: unknown arg ''--set-dscp'' TOS target is working fine, but I want to create different codes for EF and AF classes in a diffserv

Hello, As it is well know that CBQ is the class based queue. But i am confused on the word "class" now, especially it is used in Diffserv. IMO, different classes should mean that there are different kinds of traffics, so the class should be difined by the parameters (such as bandwidth, priority..) the traffic wanted. That is, using cbq we can define different kinds of traffics which

Hello, As we know that there are four kinds of AF in diffserv architecture, and each kind has three different priorities. So, there are 12 different kinds of AF, is it right? Of course, each AF has its recommended DSCP value. Then, we know the AF is classified into four differnt classes, such as AF1, AF2, AF3, and AF4. But in a Diffserv domain, and in the core router, there will be a classifier

Ok, the script is attached... I'll post it on www.generationd.com when I have a chance. If you have any updates & improvements please email them to me! (The command line parameter handle is pretty stupid - just grew from testing to production without cleanup).

Can anyone comment on the DSCP quality of service settings on your Asterisk server? The network we're setting up has data on the default VLAN, Asterisk server and phones on VLAN 4, and we're using Polycom phones with a PC hooked up to the phone's pass-thru port. What iptables settings are you using on the Asterisk server for DSCP? What are your Polycom DSCP settings? We're using

Is it possible to set QOS/COS/DSCP on IAX packets? I see some parameters in sip.conf but not iax.conf Thanks -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20091001/abf55045/attachment.htm

Hi all, I am new-ish to Linux tcng and am struggling to find the resources and know how to implement what I need. What I have is a PC with 2 interfaces and a control program on that PC. In the control program I can specify an IP Flow with source and dest IP address, source and dest port, and a QoS class (1-5 which can be mapped to a DiffServ class) - in the control program I want to be able

Hi all, I am wondering if anyone can help me to resolve a problem. I am trying to use tc command in linux to drop udp packets of specific diffserv value. I am able set diffserv value successfully in the udp packet using command:- [root@scotch src]#iptables --table mangle --append OUTPUT \ --out-interface eth0 --protocol udp --source-port 5060 \ --jump DSCP --set-dscp 8 but i am not able to

Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using. The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work? Any

hi, I am currently working on a project on implementation of diffserv testbed using tc utility from iproute2 package. i am struck in the dsmark qdisc which allows to mark the DSCP field in IP header at the first hop router. Once the packets are marked at the first hop , how to schedule them at the outgoing interface of the router.What i mean is after creating classes for each DS value, how to set

Hi, I know that this question may NOT belong to this Mailing List, but nevertheless, I hope I will get some help :) After having worked with DiffServ on Linux, I want now to try marking IP-packets in their DSCP header under Windows OS (e.g. WinXP).
