http://www.sslshopper.com/ssl-checker.html I use this to test, if your OpenSSL install doesn't have the chain certs it can't verify the chain unless you provide it. On Tue, Aug 26, 2014 at 12:21 PM, Szeto, Steven <steven_szeto@mitel.com> wrote:
I have also had issues with using third party certs with FreeSwitch. If I generated my own certs and used them with a FSClient, I can get the FSClient to register via TLS to my FreeSwitch server.
However, I was unable to install the generated certs into my SIP phones and get them to register with my FreeSwitch server. I think there is a bit of work required here to get FreeSwitch to be a bit more flexible in its TLS registration protocol.
Ideally, we should also be able to install multiple root certificates for various phones and allow these phones to register with the FreeSwitch server. As far as I am aware, multiple root certificate support is not supported.

Hi,
The story so far :
• I've installed new certs • checked config in vars.xml is pointing to the right place • restarted freeswitch entirely • it is still using some sort of internal certificates ?? cafile and agent contain my certs and not those referred to in the openssl output ??
What am I missing ??
Thanks
Tim
