What are IP Phones?

IP phones, also called VoIP phones, SIP phones, Internet phones or broadband phones, are designed to connect directly to the Internet through a local broadband or WIFI connection.
Internet phones (IP) can be wired and wireless (Wi-Fi) IP enabled.
The big three manufactures of VoIP phones today are Cisco, Snom and Polycom. Some Cisco IP phones also offer video, however both parties need to have a video IP phone to make a video call.
VoIP phone functionality can also be implemented with a PC or laptop if you have the Softphone software and a headset or microphone and speakers.

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News 1. Security Considerations IBM advises customers who are using SSL, that the most secure way to do this is to use recognized Certification Authorities to sign their certificates. Ensuring secure transfer of information is the main purpose of SSL. This integrity must be properly observed when setting up SSL. You should always be certain who has signed each of your SSL certificates, who has had and who continues to have access to them. The first secure way to generate certificates is to generate a certificate request, on each system or machine that uses SSL. This request has to be signed by an external Certification Authority before it can be used. Getting certificate requests signed by a CA is secure, because during the signing process at no point do any files contain the certificate's Private Keys. This principle is vital to SSL security. Signing certificates in this way is covered...
