Hi, We are using 3cx 15.5, along with Cisco SPA 504G (Firmware version 7.6.1), the issue that I'm finding is that I'm not able to re-provision the phones by going to Phones > Reprovision. When I select the phone and click on Reprovision, nothing happens. But when I click on Reboot, the phone reboots and gets registered again. Also, I have to manually provision all the phones by going to the web ui. I tried using the steps provided in the link https://www.3cx.com/sip-phones/cisco-spa501g/ and built a url by following the steps. Eventhough the phone showed the outcome provided in the link, it didn't reboot on itself as mentioned in the article. Can anyone please let me know what could be the possible issues? Thank you.
