Building a fantastic audio conferencing setup for the cheap
September 25, 2012
One of the most popular activities at any modern office office is the conference call. Of course as time and technology allows, the conference call has morphed into audio/video/web conferencing. When you’ve only got one person on each side of the “call”, it really doesn’t matter what hardware or software you use… or the call quality. Of course, it’s almost never just one person on a side and each person you add to the mix necessitates increased call quality in order to maintain a productive meeting. That means either buying an expensive finished solution… or doing it yourself.
Recording high quality voice prompts for Asterisk
February 21, 2012
Recently I’ve found myself setting up a new Asterisk box, which is oddly one of my favorite tasks. IP Telephony (or VoIP for the rest of us) is quite fun to play with. Office phones and IVRs are something that everyone uses. It’s really nice to see something you have built used day in and day out without anyone ever noticing it. Asterisk doubles this fun because A) You can make the phone system do whatever you can think of (as long as you can program it) and B) You can build a system that rivals the functionality of the BIG corporate systems… if you know what you’re doing.
Dial-Peers on Cisco 3600
January 25, 2007
When I setup the Cisco 3600 in the office to work with asterisk as our FXO ports, I needed incoming and outgoing capabilities. In was easy enough, but out was more tricky because you need to setup specific dial-peer plans. Well for the longest time I had 3 different sets of rules per port (911, Local & Longdistance). Luckily I only had 4 ports, for a total of 12 rules. I thought that was stupid, but never got to fixing it.

NuFone is once again trying to screw me over — this time for 7cents. I dont belive these people, more specifically that one person. I’m preety sure NuFone is just one person. Their service is really bad, and I cancled it after a week of using it last… January. I cancled my account then I asked for a partial refund, wouldnt do it. Filled a paypal complaint, didnt go very far as usual.

Brought a new 7960 online today in the office — and it paper weighted itself. It loaded up the Universal Application Loader, but then refused to load the new SIP firmware. I found two things that are useful, first Voip-info.org has a useful bit and second — pay very close attention the the TFTP server logs. In the end, copying the .sb2 firmware image to .sbn was the magic trick (and possibly a few extra config files they mentioned on the page above).
When working with Cisco
April 26, 2005
If your making changes you want latter — Suggestion: Always write the configuration to memory. We haven’t been using our old voip router recently (newer gear for cooler stuff), so I was playing with it a while back (you may remember FXSs are a go! ) — Except I forgot to save my changes to memory before I was done. Sigh. I’m glad I wrote that blog entry, most everything I need to get the system going happily was there.
Sigh and DoubleSigh

Surfing the RSS feeds this morning and I found two new intresting topics to bitch about in the wide wonderful world (WWW) of technology. First off is a moving article from ars technica, about the new Google mobile search. Ars’ first and foremost has a problem picking a side, their poking at it claiming that it could be evil, but its not such a bad idea. Make up your damned minds.

So this bit was posted on /. . I thought I’d relate the information seeing how its rather nifty guide. Kerry Garrison used [email protected] (which I’ll admit I’ve never heard of before, But I’ve seen it done similar before) to build a PBX. I think the real key of this installation is that [email protected] comes with AMP already built in and ready to go. This is a really nice feature seeing is how Asterisk doesn’t understand config files.
FXS's are a go!
January 31, 2005
Well its amazingly difficult to find documentation about how to make FXS’s work with Asterisk. I happen to have 4 FXS ports on the Cisco 3640, the same one that has four FXO ports. Below I’m including my configuration for use by others. The FXS port is configured as extension 600 (the Asterisk side configuration is also include). Cisco 3640 Config voice-port 0/0/0<br /> station-id name test<br /> station-id number 600<br /> !
Yea for PBX's
January 30, 2005
So several months ago I moved our small office over from a Windows 2000 box running some Microsoft built-in IP telephony software, to an Asterisk PBX. Now I’ll admit I knew almost nothing about Asterisk, or Cisco hardware. Since then I’ve made major strides. Yesterdays project was to see if I could get a Cisco 3640 router with 4 FXO ports to connect to Asterisk. I did, and I got it to work.

So your looking into finding cheap long distance for your IAX2 compatible system (for those that don’t know what I’m talking about, I’m talking about VoIP terminator services for your Asterisk PBX). I’ve been playing with a few of these services recently. I have to say that VoipJet works. They aren’t anything fancy, you have to prepay, but their systems work. You can fake your own Called ID, and all those good services.
