[on-asterisk] TAUG Meeting; Guest Speaker Downtown Location; 7pm, Wed July 25th
NOTE: This talk will be DOWNTOWN at John St. and Wellington St. West This Wednesday July 25th, we have a guest speaker coming in from out of town, so I hope everyone can make it downtown. We are being joined by Andrew Gillis, the creator of TrixBox / [EMAIL PROTECTED] and he will be giving a technical talk on TrixBox. Some background on Andrew: Andrew Gillis has been working with VoIP since VoIP became commercially viable in 1998. He was a Senior Systems Engineer at several VoIP startups including Octave Communications developing VOIP voicemail systems. He became an independent consultant, deploying worldwide roll-outs of VoIP PBX systems to companies such as Liberty Mutual. In his spare time, Andrew created [EMAIL PROTECTED] as a fun project to build home PBX systems for his friends and business associates. [EMAIL PROTECTED] took a life of its own and grew to be the largest source forge in the world with 80,000 downloads a month. A bit about Fonality, the sponsor of TrixBox: Fonality became aware of [EMAIL PROTECTED] and was impressed by the growing active community. In an effort to give back to its open source roots as well as becoming a lead generation tool for Fonality's PBXtra product, Fonality acquired [EMAIL PROTECTED] in October 2006. Fonality renamed [EMAIL PROTECTED] to trixbox. Andrew continues to grow the trixbox community and the products the products that surround it. When: WEDNESDAY July 25th, 2007 7:00 PM - 8:30 PM Where: Room 308 Metro Hall 55 John St., Toronto, ON (Google map link: http://xrl.us/25xp)a Driving: There is a large parking lot just a bit north at King Street and John Street. (Maybe there's parking closer? I'm not familiar with the area) TTC: Take the subway to St. Andrew station, then walk through the PATH to Metro Hall, or walk above ground 2 blocks west. Afterwards: We'll socialize grab a bite at a local pub - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[on-asterisk] Re: Hybrid phone ?
Hi , I am looking for a good analog phones with 2 or more lines so that I can bridge a VOIP line to a POT line. By bridge, I mean call forward and conference feature. Yes, I know I need an ATA too. Since they do now make such an hydrid phone, Technically, I guess this is my only option. Any other suggestions or phone model is appreciated. Thanks in advance, Richard - Original Message - From: John Van Ostrand [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, July 11, 2007 2:52 PM Subject: Re: [biz] Hybrid phone ?

So, the phone can receieve calls, make calls and even conference calls from PSTN and VOIP channels? One solution that doesn't directly fit your question is to use an ATA and a regular phone. The Linksys SPA-3000 (nee Sipura) that I purchased last year did just that. It has a POTS port and can be configured to route calls to POTS or VoIP. It's dialplan option meant that certain phone numbers could be directed one way or another or one could dial an 8 for a POTS line and 9 for a VoIP line I also had a GNET IP phone at one time that was supposed to do that as well. One phone seemed to generally work (poor sound quality) and the other gave problems before and after being sent away for repair/replacement. -- Register for the Ontario Linux Fest Conference today!

[on-asterisk] Cordless System for Home... DECT - Asterisk?
I just want to know if people have any suggestions on a setup for home. My two line Siemens 2.4Ghz telephones (currently have 8 of them with answering machine) is dying and I'd like to replace them with a new system. Each handset has it's own set of problems and it's long overdue for replacing the whole thing. I have been looking at phones at Futureshop (DECT phones), but I need to have more than 4 phones (at least 6 phones). The few phones that support that many handsets only have 3 or 4 phones with the pack. I'd buy two packs but seems to be a waste. Two lines is not mandatory... I am thinking that maybe it is time to implement a cheap Asterisk box, but I don't have a budget to sink $$$ into cordless SIP phones (would love to though). I'm also concerned about running a full time computer just to answer my home phone line. Seems to be a waste as well. Any suggestions on a good way to implement Asterisk/Trixbox so that it takes little/no power? Any suggestions on cordless phones?

I think I remember a TAUG member doing a clinic on setting Asterisk up on a Linksys router, that might work for you, Mark. -Original Message- From: Chuck Mariotti [mailto:[EMAIL PROTECTED] Sent: Monday, July 23, 2007 11:51 AM To: [EMAIL PROTECTED]; asterisk@uc.org Subject: [biz] Cordless System for Home...

[on-asterisk] VOIP Bandwidth - Calculation
Hi, For a 10 SIP /g729 simultaneous use. What is the Best internet connection recommended. DSL or ADSL What is the upload and download speed required? How to calculate the the band width? ( g729a - 8 kbit/s 10 ms frames) if u can guide me greatly appreciated. Thank you -- Lloyd
RE: [on-asterisk] VOIP Bandwidth - Calculation
G729 is no wear near 8kbits with overhead its more along the lines of 32kbps unless you start trunking your channels then it gets smaller. DSL, and ADSL are terms dsl is really nothing than an acronym for digital subscriber line with out a letter in front of it. ADSL - mean asynchronous usually the grade you get as a standard hight speed it has good downstream but poor upstream, voip requires bandwidth in both directions :) SDSL - synchronous dsl, sends and receives at the same speed -- this is really what you want. and then there are ldds loops which you can get from select carriers, and the modems will have some cool names like this HDSL GHDSL (last one i saw of this did 16megs in each direction :) ) There are many more flavors than that but those are your basic ones. If you have a really good adsl connection you can squeeze 10 g729 calls but latency to your provider becomes a major factor. G729 sounds good it the latency is low and there is no packet loss if the latency is high it will sound worse than gsm. Hope that helps some.

Re: [on-asterisk] VOIP Bandwidth - Calculation
As Phil described, its much more than 8 kbps, and the lower the frame rate, the more bandwidth it takes due to the packet overhead. While turning up our softswitch, we did a bunch of testing with different codecs at different sample/frame rates on ethernet. Here are my *real world* results: g711 (ulaw) 10ms frame ~= 126.5 kbps 20ms frame ~= 95.2 kbps 30ms frame ~= 84.7 kbps 40ms frame ~= 79.6 kbps g729a (8 kbps) 10ms frame ~= 70.5 kbps 20ms frame ~= 39.2 kbps 30ms frame ~= 28.8 kbps 40ms frame ~= 23.5 kbps We didn't test GSM. So, most ADSL providers (including us) offer sync rates at speeds up to 800 kbps, however that speed is if the traffic is ATM (which it isn't), so by the time you add IP/Ethernet overhead, the 800 kbps speed usually gives you a payload somewhere around 670-690 kbps. So divide that by one of the numbers above and round down and you will have your *theoretical* max simultaneous calls assuming the connection is only used for VoIP. Now throw in a few users and their email and web traffic and the number starts to go down. Hope this helps you out.
