Re: [asterisk-users] ADSL routers with integrated SIP QoS for otherdevices
In my experience I'm using a comtrend CT-536+ It's a broadcom 96348GW model 266Mhz Mips r4K compliant CPU 16MB RAM and 16 MB flash, adsl2+, 4 port ethernet switch, usb 1.1 and .g type wireless. I'm using an Asus WL600g based firmware because de uclibc and toolchain version of cross compiler, but there are others with diferent capabilities like Ipsec etc.. I know a t least of Telsey one. Mine is a 2.6.8.1 Kernel version with time infraestructure for mips backported from 2.6.16 kernel (High resolution timers), I have to check if it's worth... It has Iproute2 and iptables and ebtables, dscp capable and diff-serv qos. Zaptel 1.4.1 with only ztdummy zttest and libtonezone, and a mini version of asterisk 1.4.2 but I'm working on a sqlite2 and realtime capable one... No h.323, not moh although the usb can be used for a memory stick, ah... It's used for callshops with yuxins sip/iax phones, no TRANSCODING just g.729 end to end, we use this to bridge sip-iax2/IAX2--Internet--IAX2/SIP---Lucent Compact Switch--Intl PSTN Carriers because of trunking capabilities El Miércoles, 2 de Mayo de 2007 14:28, Mike Dent escribió: On 5/2/07, Tim Koehler [EMAIL PROTECTED] wrote: Hi, I can agree for smaller installation/home offices the Linksys WRT series is pretty good (I'm using this at home).

Re: [asterisk-users] ADSL routers with integrated SIP QoS for otherdevices
Hi Mike, I'm using a Linksys WRT54GS (older model, I believe V1.1 or 2.0). For the office (exhibitions, testing purposes) I ordered 2 Buffallo routers (directly from the DD-WRT page, preconfigured with DD-WRT). I like to support this guys work and pay a couple Euros more for the router. The Buffallo Router also works very smooth, the coverage is pretty impressive (close to a DECT handset). At home I have a SIEMENS ADSL2+ modem given from my operator (I get around 12-14 MBit/s downstream and 1,3 MBit/s upstream). Unfortunatly it just went up in flames yesterday, so since yesterday I'm using the router as WLAN Client Bridge to my neighbours WIFI. Before that ADSL2+ Line I had a 2 MBit/s SDSL line with a Cellpipe Modem. Before that I also had 2 different other providers with 2 different other modems. So many different modems and no issues on this side. Any more questions? Cheers Tim Tim, great to see your participation in the Asterisk list and nice to see you using the dd-wrt firmware. Might I ask which model WRT you are using and if you use a seperate ADSL modem which one?

Re: [asterisk-users] ADSL routers with integrated SIP QoS for otherdevices
Well on the other side of things there are plenty of adsl equipment running linux and qos capables and customizable firmware. Normally you can get the source of the device with binary drivers of devices like adsl wireless or ethernet switch.. but as long as you stay with the linux version and the tollchain provided you can even compile ztdummy and asterisk to work as a soft pbx. Normally thesse devices are broadcom MIPS based or Texas Instruments AR7 ARM based El Sábado, 28 de Abril de 2007 19:55, Dan Austin escribió: Andrew wrote: On Saturday 28 April 2007 11:22 am, Chris Bagnall wrote: Thanks to all who replied to my thread a few days ago SIP devices with packet loss tolerance.

If you're curious, I have my rc.tc script for Linux up on http://mixdown.ca/~andrew/rc.tc. It's loosely based off of wondershaper, but works much better, IMO. It does host-based prioritization for VOIP, puts mail just underneath bulk traffic, and P2P beyond that (if you have the p2p connmark stuff set). I can completely saturate DSL links with the S518 with this config without appreciable VOIP degradation. I'm using something similar. The missus can talk to her mother (in rural Japan) over IAX while I am using a IPSEC tunnel to work, and doing heavy downloads. Even without an S518, this script works well with external ADSL/cable modems. You may have to play with the upload rate; some cheap ADSL modems will start blocking your upstream traffic beyond as little as 50% of the upstream rate. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users -- Francisco J.
