[Freeswitch-users] TLS and SRTP commercial certs go in which file?

Mon Sep 18 08:03:47 UTC 2017

Hi Bipin,

Putting the same into all 4 pem's certainly works, and that's correct no intermediary or root ca required providing you have the public and private key in your pem files.

The wiki article for SIP_TLS could do with being updated, but I don't know exactly what each of the 4 certs are used for.

This is my best guess at what each of the certificates are used for.
agent.pem - FreeSWITCH public server cert
tls.pem - Used for TLS communication
dtls-srtp.pem - Used for DTLS\SRTP communication
wss.pem - Used for WebRTC communication

Hi,

Thanks for that info so if I understood it right the agent.pem file will have my cert and key inside it only and no intermediary or root ca cert is required at all, but what goes in the tls.pem file?

Hi Bipin,

We've found that these are the certs which FreeSWITCH will use, the pem file will need the public and private key (same as your wss cert). You'll also need to make sure the user for FreeSWITCH has read permission to the certs.
agent.pem
dtls-srtp.pem
tls.pem
wss.pem

FreeSWITCH doesn't seem to need the intermediary and root cert of the CA.

Here are some of the TLS parameters you might also want on your SIP profile.

Name: tls
Value: true

Name: tls-bind-params
Value: transport=tls

Name: tls-cert-dir
Value: "Your Cert Directory Path"

Name: tls-sip-port
Value: 5061

Name: tls-verify-date
Value: true

Name: tls-verify-depth
Value: 2

Name: tls-verify-policy
Value: all|subjects_all

Name: tls-version
Value: tlsv1.2

hi,

when i setup verto on my server i used commercial certificates with wss.pem containing the following and all that works brilliant:
-----BEGIN CERTIFICATE-----
<lots of gibberish from the actual certificate>
-----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY-----
<lots of gibberish from the actual certificate>
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
<lots of gibberish from the intermediate certificate>
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
<even more gibberish from the root certificate>
-----END CERTIFICATE-----

now i want to use the same certificate for TLS and SRTP and i was reading the docs and it mentioned to create a agent.pem file with the actual server cert and key but where do i copy the intermediatory and root cert of the CA, which folders do both go in and with what filename?

any help is appreciated
