John usually talks to audiences who are very unhappy because they don’t own the network nor have control over QoS, but WISPs and other ISPs attending ISPCON are in control and do own the network. The voice they sell can be as good or bad as they are willing to enable with the power they have.

Asterisk is a viable tool to provide voIP. Often used as a telephony toolkit, as voie application, set of APIs, and PBX. Decide to make the call go over SIP or PRI or SS7 link. The APIs give call control over other interfaces for web 2.0 apps, pre-existing database to make calls out… The PBX is very popular worldwide.

“You’re using Asterisk. You just don’t know it.”

Asterisk experienced more than a million downloads in 2008. Watch the video for more info and stats. This video was recorded by me Suzanne during ISPcon 2008.

If you the ISP or WISP is not using and selling Asterisk-based product, who is? That’s a question Todd posed. I would say, “Someone is. No, many are.”
