IQ Labs announces the release of PBX Testing Framework. This software is intended to test existing call-center PBX, and is distributed under GPL license. Currently it allows SIP testing, but implementing IAX (and even Zap) shouldn't be a problem, as the framework is based on Asterisk, and can do anything the Asterisk does. Please see README file included for configuration and scripting samples. You can download it from: http://ftp.iq-labs.net/pbx-test/pbx-test-0.1.0.tar.gz Please give us a short feedback if you're successfully using it. For any questions and improvements you may contact voip at iq-labs.net Regards, Atis Lezdins VoIP Developer IQ Labs Inc.
