The current Sangoma (Digium) D-Series phones and the Switchvox Mobile App use an SSL certificate to encrypt phone configuration messages which will expire on May 28th, 2021. Unless the upgrade instructions below are followed, the phones and app will no longer be able to get configuration information from Asterisk, FreePBX, PBXact, and Switchvox and will not be usable after that date
Who is affected
All Asterisk based systems using D-Series phones with DPMA are affected, including:
FreePBX systems using D-Phones and the deprecated Digium Phones module (Connectivity → Digium Phones)
FreePBX and PBXact systems using D-Phones and using Endpoint Manager with DPMA enabled
If not using Sangoma (Digium) D Series phones, you are not affected.
Affected DPMA Versions
Any System running DPMA versions older than the following are affected:
DPMA 3.4.13 for Asterisk 11, 13, 15, 16
DPMA 3.5.7 for Asterisk 13, 15, 16, 17, 18
DPMA 3.6.2 for Asterisk 13, 16, 17, 18
