Introduction to SCCP Security and Connectivity

SCCP (Skinny Client Control Protocol) controls telephony gateways from external call control devices called Call Agents (also known as Media Gateway Controllers).

Connectivity and network level security for SCCP-based VoIP communication is supported. All SCCP traffic is inspected and legitimate traffic is allowed. Attacks are blocked. Other firewall gateway capabilities are supported, such as anti- spoofing and protection against denial of service attacks.

The validity of SCCP message states is verified for all SCCP messages. For a number of key messages, the existence and validity of the message parameters is also verified.

SCCP Supported Deployments

These SCCP deployments are supported:

Important - NAT on SCCP devices is not supported.

Call Manager in the Internal Network

Call Manager in an External Network

The IP phones use the services of a Call Manager on the external side of the gateway. This topology enables the use of the services of a Call Manager that is maintained by another organization.

 

Call Manager in the DMZ
