How many extensions (phones) can I have?

AskoziaPBX was developed for the requirements of small and medium sized companies. We recommend that you not use more than 200 extensions. This is what we’ve designed the software for and this is where our testing stops. However, there’s nothing in the software that prevents you from using more phones.
