Complete this form to have your CRM system considered for development of a plugin. Note that unless the system is widely used with tens of thousands of users, we are unlikely to develop it. The form can serve though as a way for you to collect the right information needed so you can understand how easy it is to develop a plugin for it. You can then do it yourself or outsource it to a professional (you can post your request on the integration forum listed below). If your CRM has a modern REST API then its much quicker to develop it. If you are a CRM provider yourself, you can use this form to contact us and submit your integration for listing within the 3CX software. Some important links:
For larger projects 3CX can also do the integration at a charge.
