SSL Certificate Expiration Overview

What is the Asterisk SSL Certificate?

An SSL certificate is a digital certificate that confirms the identity of a website and allows for a connection that is encrypted. SSL is short for Secure Sockets Layer, and represents a security protocol. This means that it is the layer of protection that exists between a web browser and server so that businesses can ensure that transactions online are safe and can effectively protect sensitive information from their customers. When you go to any website online, the SSL certificate is usually indicated by a padlock next to the webpage name in the search bar.

D-Series telephones and the Switchvox Mobile Softphone possess an embedded certificate that is used to encrypt their communications with a Sangoma phone system server.  The certificate will expire on Friday, May 28, 2021 at 4:45:20pm EDT (GMT -5).  If this certificate is invalid, D-Series phones and the Switchvox Mobile softphone are unable to provision against any Switchvox or DPMA-equipped system.  There is no in-place mechanism for remotely forcing an update on a server that will provide remediation.

What Happens After an SSL Certification Expiration Date?

After an SSL certificate has expired, you will no longer be able to communicate via a secure, encrypted HTTPS connection. All of your (or your customers’) data will be sent in plaintext, leaving their (or their customer’s) information vulnerable to any possible attackers on the network.

 What is Affected By Certificate Expiration?

  • All released versions of Switchvox that support D-Series telephones and/or the Switchvox mobile softphone including versions 5.5 through 7.6.1.  
  • FreePBX and PBXact systems using the deprecated “Digium Phones Add-On for FreePBX”
  • FreePBX and PBXact systems using the “DPMA” option for Endpoint manager
  • All released versions of DPMA used with open source Asterisk. 

Remediation Plan for SSL Certificate Expiration Date

Sangoma has produced new versions of DPMA, Proxy, D-Series telephone firmware, and Switchvox mobile softphone that remediate the problem.  Administrators (except Switchvox Cloud and PBXact UCC) MUST take action prior to the expiration date.  For Switchvox users on 7.x, the new firmware is included in Switchvox version 7.6.2.  For Switchvox users on 6.x or 5.x, the new releases are 6.8 and 5.12 respectively.
