Programming the Asterisk open source PBX via the Asterisk Gateway Interface (AGI) is a fun but exasperating exercise for the telephony programmer. It is fun since it can make a telephone dance, but frustrating because errors and debugging information can be difficult to catch since status information arrives on multiple channels: audible, Asterisk console, and STDERR.

"We're a completely bootstrapped company," says Mike Oeth, founder and CEO. "We were never locked into a business plan that was sold to investors." He says Junction is successful because it has been able to follow its customers' desires with open source.
