If you've wondered how secure the TLS implementation is in Grandstream VoIP phones, you are not alone. They have some functionality that is ostensibly supposed to allow the administrator to add certificates. However, there is no method to find what certificate authorities the phone already blindly trusts.

I've had a Grandstream tech support ticket open for over four years on this topic. The people there don't seem to understand the security implications; from their flawed perspective, the user is just supposed to buy a SSL certificate for a corporate SIP server and that makes it magically work.

This careless attitude to security is reflected in their CA certificates. They've thrown in everything and the kitchen sink too... including some used by developers that should only have been internal to Grandstream. Any one of these can be used as a backdoor to hijack the phone's traffic and make it erroneously think that it is connected to a legitimate server.

A green color code indicates presence in the current (2019-01-23) Mozilla certificate list. Red indicates the opposite.

Note that green doesn't necessarily make it trustworthy; it just puts it on a similar footing to Mozilla Firefox. Also note that there is no evidence that the phones are capable of Certificate Revocation Lists, so any certificate ever issued by these CAs is blindly trusted.
