Linux Bridge + QoS Shaper HOWTO available
I've created a pretty complete HOWTO on creating a Linux Bridge (using Fedora) to shape LAN <--> WAN traffic. It includes installation instructions, a script to configure the bridge (which you install as a service), and 2 scripts to configure the network interfaces using traffic control. http://www.burnpc.com/website.nsf/all/3a64a6369757819686256f960068ad75!OpenDocument If anyone

QOS / Cisco / Asterisk
We're trying to PQ (Priority Queue) packets on a Cisco using ACL's. What we're trying to avoid is hardcoding the IP address in the ACL. We were trying to match by TOS set by Asterisk however it seems we've run into a snag where the packet TOS tends to get reset somewhere on our network. Has anyone had this issue? We're running Cisco everywhere inbetween (even the switches). Is

Is Gigabit Ethernet necessary?
For an office that is using VoIP phones to connect to Asterisk, is gigabit ethernet really necessary for the Asterisk box to connect to the switch? I know that I won't even approach the limits of 100 Mbps, but would gigabit help with latency / collisions when several calls are underway? The fact is, anything going outside the office will be over a data T1, so intuition tells me that 100

Router Recommendations Please
Hello all, We've discovered that VoIP (IAX2) + Citrix + Video is pegging the measly CPU on the Netopia router our ISP provided. We've got 3Mb/3Mb and will increase to 4/4 next year. The Netopia simply breaks out our WAN IPs, and we've got a switch hooked up to it on the inside (Actually I've got a QoS box in-between). ------------- | Internet | | on Cat5 | -------------

Linksys RT31P2
Has anyone tried out the Linksys RT31P2 with Asterisk? Seems like a really great solution for remote users... even supports QoS. Too bad it doesn't also have VPN functionality built in.

IP Cop as a firewall and QOS
We are looking for a good firewall replacement which will basically do pot blocking and QOS. Our current solution just plain stinks.. We basically need to handle the traffic of a few web servers, mail server and asterisk box. The most traffic this device will need to handle is what can be shoved through a T1. I don't mind buying an appliance to get something solid but IP Cop just looks

Solution for 1 time blast of 200, 000 recorded calls
Hi, I'm helping out with a political campaign and would like to use asterisk to blast out about 200,000 calls with a short message from the candidate. Provider: I'm thinking voipjet may be a good solution? Hardware setup: I will have access to several T-1 lines so I would just want to set up the dialers to limit the number of concurrent calls and so forth. I found teleyapper on

Polycom FX Video Unit - asterisk-oh323
I'm installing an office in a couple of weeks that will have some nice Polycom FX video units in the conference rooms. I'm thinking that with asterisk-oh323 http://www.inaccessnetworks.com/ian/projects/asterisk-oh323/#section2 I should hopefully get the ability for phone users to dial an extension and participate in video conferences, or just simply phone conference with users in the

Dynamically Choose Codec for Bandwidth Management
Is there any way to set Asterisk to choose what codec to allow for a new call based on current usage? In other words... be able to define a max number of ulaw calls, then after that only allowing g729? The idea here is that in general, a T-1 should be enough for our offices to have phone + citrix + some video (got good QoS in place already). But for usage spikes, user experience would be kept

destroy SIP channel??
I've got a SIP channel that appears to be hung up. It's an extension that records a .gsm file and fortunately the recording has stopped. I tried zap destroy channel but I guess that doesn't apply to SIP channels. Any ideas? I issued a restart when convenient but figure there must be a better way.

MeetMe & ztdummy
I'm running into a bit of a problem setting up conference calls. The box I rent at a colo doesn't seem to have USB hardware.... When I try to load usb-uhci I receive a "device does not exist" error. Which means I can't load ztdummy.... The system has a rtc clock module, so zaprtc won't work... (which I'm scared to unload rtc because I don't have physical access

Garbled one-way audio only with ulaw
For some reason a couple weeks ago users began experiencing garbled audio in one direction when dialing out via our VoIP provider. This happened at multiple sites simultaneously. The VoIP provider doesn't think it's their problem. If I switch to another codec so that Asterisk transcodes everything is fine. On conference calls (where Asterisk gets in the middle to relay ulaw to all

asterisk-oh323 and outgoing call
Hello. I'm try to set up asterisk for making outgoing calls with oh323 channel driver version 0.7.1 with Asterisk CVS-1-01/09/05-01:41:37. Our provider uses Mera MVTS softswitch and supports only H.323. We don't use gatekeeper for connection but provider requires SOURCE PHONE NUMBER for route out calls and I don't know how I can specify this number. Call with this string exten

Help? Router/Bandwidth throttle needed.
I hope this list is still active. I''m an experienced Linux Sysadmin, but I haven''t done much in the way of routing. Due to a decision made by my higherups, I need to jam a computer between my ISP and my LAN to do bandwidth throttling. My current setup: 1 Crappy Cable Modem (7Mb/768Kb connection) with a static IP. 4 servers (all have static, routable IPs) - One of which is

PRIO / CBQ / HTB queue drop algorithm
Hello all. I''ve been struggling to QoS VoIP at our site and have a successful implementation at this point. Basically I had to set aside enough bandwidth for VoIP by placing all other traffic behind an HTB (multiple classes and queues behind it). Everything is fine.

drive space for voice mail
Drive space for voice mail I've looked in the dimensioning information on voip-info.org but can't find any hard information on the amount of drive space the various codecs use. Since we would eventually like to support web-based voice mail retrieval, I'm thinking of the wav format. I've specced out 2x160GB drives in RAID-1 (software RAID via Linux) for the box. It will be

PRIO inside HTB - trouble attaching filters correctly?

load balancing between two default gateways
Hi list gurus, long story short we have firewall machine which is the default gateway for our clients and firewall send traffic out to Internet via cisco router. On cisco we have two serial interfaces 1Mb and 2Mb. On firewall #route add default gw xxx.xxx.xx.xxx (for 2mb) #route add default gw xxx.xxx.xx.xxx (for 1mb) and the same rule for Imb link route packets via these two links. However I

Classful Queuing
OK, I''m stumped. I''ve read through most of the LARTC HOWTO and have yet to find a basis for what I need to accomplish. I have a Linux box that controls access to and from the Internet at my workplace. We have a number of remote employees that connect via PPTP and IPSEC to the office''s internal network. Some of these remote employees are currently using SIP phones.
