Regarding IP telephony the subject VoIP Security becomes more and more important. VoIP must have the same confidentiality, authenticity, availability and integrity as traditional telephony solutions.

Buzzwords to improve the above mentioned properties are SPE, TLS, SRTP and PKI.

HiPath platforms like HiPath 3000 or OpenScape Office MX use the most current technology to protect voice and signalling data from unauthorized access.

Please have a look also at the administrator documentation to IP phones of the optiPoint and OpenStage families and the service documentation for the IP platforms.


Signalling and Payload Encryption (SPE)

Activate Signalling and Payload Encryption (SPE) on a OpenStage 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 LocalAdmin: Administration -> System -> Security -> Signalling main = TLS
  • Configure transport mode WEB: Admin -> System -> Security -> Secure H.235 main = TLS
    • 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 validation main can now be enabled, in this case certificate must be downloaded via DLS
    • If you use the feature SRSR. And the standby System is using SPE too, then please configure also Secure H.235 standby(WEB) -or- Signalling standby(LocalAdmin). And Certificate validation standby (if used)

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
