Setting up ipbx

Configuring SIP/TLS

Creating a Key File and CA

$ openssl genrsa -des3 -out ca.key 4096

$ openssl req -new -x509 -days 365 -key ca.key -out ca.crt

Sample CA Cert

 Country Name (2 letter code) [GB]:US

 Locality Name (eg, city) [Newbury]:New York
 Organization Name (eg, company) [My Company Ltd]:Taridium
 Organizational Unit Name (eg, section) []:engineering
 Common Name (eg, your name or your server's hostname) []:Taridium CA www.taridium.com
 Email Address []:info@taridium.com

$ openssl genrsa -out key.pem 1024

Certificate Signing Request

$ openssl req -new -key key.pem -out req-ipbx_taridium.csr

Country Name (2 letter code) [GB]:US
 State or Province Name (full name) [Berkshire]:New York
 Locality Name (eg, city) [Newbury]:New York
 Organization Name (eg, company) [My Company Ltd]:Taridium

Creating a Self-Signed Certificate

To create the self-signed certificate, do the following:

$ openssl x509 -req -days 365 -in req-ipbx_taridium.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out cert-ipbx.cert

Installing the Certificate

$ cat key.pem > asterisk.pem
$ cat cert-ipbx.cert >> asterisk.pem

$ mv asterisk.pem /etc/asterisk/
$ chown asterisk:asterisk /etc/asterisk/asterisk.pem

Setting up your Device

ipbx Configuration

Device Configuration

Aastra

1. Place the ca.crt file in your Aastra provisioning directory (on ipbx this is usually /var/www/html/prov)/
2. Configure the Trusted Certificates Filename to be ca.crt

Counterpath Bria

Place the ca.crt file on a webserver and load it using your browser to store it in our operatings system's ca
