Would you like to evaluate AskoziaPBX for your business? We offer Diet Askozia so you can do exactly that. Diet Askozia comes with almost the full feature set of AskoziaPBX but is limited to two parallel calls. Configure it, try it out and enjoy. If you need help along the way, check out the handbook
or visit our forums
If you decide to upgrade to the full version, you can use the exact same configuration and it will just work.
