| Negotiation of security protocols to protect H.225.0 call signalling messages |
 |
ITU-T Recommendation H.460.22 defines a security negotiation mechanism for H.225.0 call signalling. The negotiated security mechanism between two entities is to be applied for H.225.0 call signalling messages before initiating a call establishment procedure. Detailed negotiation procedures, which provide the necessary security interoperability among H.323 systems, are specified in this Recommendation. The syntax of the security capability parameters in call signalling messages is also specified. |
