If you are only configuring Sangoma devices, you can abandon your paid license and use the free license to provision Sangoma/Digium devices. Open a customer service and billing ticket at https://support.sangoma.com to requst this.
Thanks Lorne. I only use the Sangoma S500 over here. I have submitted a request to Sangoma.
I haven’t renewed the license for about a year because I thought that Sangoma phones would not be affected and no action was required on my part. It was a wrong assumption.
If you use the paid version of EPM, once you don’t renew the annual maintenance, you stop getting upgrades. VS if you only use Sangoma phones, and you abandon your paid version, you will continue getting upgrades.
Unless you want to anyways pay Sangoma, which is a nice way of showing support.
