Regarding IP telephony the subject VoIP Security becomes more and more important. VoIP must have the same confidentiality, authenticity, availability and anonymity as traditional telephony solutions.
Buzzwords to improve the above mentioned properties are PKI, SPE/SRTP and TLS.
HiPath platforms like HiPath 2000 or HiPath OpenOffice ME use the most current technology to protect voice and signalling data from unauthorized access.
How to use secure VoIP on optiPoint SIP phones in general:

activate Signalling and Payload Encryption (SPE) on a OptiPoint HFA Phone
To enable security support on the optipoint HFA phones following settings must be done via local configuration or administration web page.
- Configure transport mode: Administration -> System -> Signaling & Payload Encryption (SPE)
- Configure C-TC TLS port in accordance to the CGW configuration (AMO-CGWB: (…), TYP=globif, TLSP=<C-TC TLS port>;), default: 4061
- H.225 TLS port: 1300 (fixed)
- Transport mode: TLS
- Certificate check can now be enabled, in this case certificate must be downloaded via DLS
