Goals
- The purpose of this feature is to provide media encryption for traditional SIP and VoIP environments
- Enable SRTP through standard SDP parameters, with and without need for SIP TLS
...
SDES is a method to pass encryption keys through standard SDP. Customers are looking to be able to encrypt media on SIP and standard VoIP networks. This feature will support securiting the fax media stream when using G.711 mode. It does not cover secure T.38 media and secure call-control (SIP over TLS).

| 8 | SRTP supported on by a single license keywork (Security). This keyword enables SRTP functionality on a per system basis. Add on part will need to be defined to add security to an existing SR140 deployment. This part will be added to the back office for normal order processing and will allow the end user to activate a security LAC via the current methods. The SR140 base feature license will not include Security support. Added support MUST require a seperate add-on LAC for security. | Part #951-105-20 | |
| 9 | COO Will need to be updated with changes to include the updated IPP (version 8.2.x) into the product. Will be required for both Windows and Linux. |
