I recently spent some time learning asterisk (www.asterisk.org) on linux using digium hardware (www.digium.com). There are stand-alone devices without service requirements from www.sipura.com but I haven't worked with them. I use an older kxtd 1232-1. My goal was to use asterisk to forward calls to different cell phones so I wouldn't need telco or panasonic voice mail. I also spent time learning how to integrate softphones (www.xten.com) so incoming calls will also ring on the computers where they are running. The softphones all share the available FXO ports (extensions) into the kxtd. I also signed up for the free world dialup service (www.fwd.pulver.com so incoming calls from the internet will be routed to one of the CO ports on the kxtd. I agree there are lots of ways to interpret VOIP. And getting it to work reliably can take some time.
The limitations I have found with my setup are the lack of forwarding caller id info from the incoming call back to the cell phone. This is due to my using three-way calling instead of call transfers. I can't get Qwest to admit they have residential call transfer. The second limitation is asterisk cannot forward a call to the CO line because it is basically an SLT. I was playing with a dialing application that attempts to call an extension. When you answer it will then dial the number you are trying to reach. It appears I have to do this the other way, call the number I am trying to reach and then transfer to the extension. Is there any work-around to SLT not being able to call transfer to CO lines in the kxtd? Thanks, Greg > When someone says they want VOIP, you have to find out what they are > really > talking about.
