we recently updated freepbx from version 220.127.116.11 to 18.104.22.168 and our sangoma phones stopped working.
currently all extensions work other than extensions that are sangoma phones in the endpoint manager. we have
verified that these phones have an inconsistent registration status in the asterisk CLI. we also know that
FreePBX works after using the backup config files we have from 22.214.171.124.
we can try to fix this issue on our end but thought Sangoma/Asterisk team may have more info about what changes
between 126.96.36.199 to 188.8.131.52 could have caused this issue.
