CCiscoLineDevSpecific | +--CciscoLineDevSpecificUserSetSRTPAlgorithmID Procedure 1. Call lineNegotiateExtVersion for the deviceID of the line that is to be opened. (0x80070000 or 0x4007000 with the dwExtLowVersion and dwExtHighVersion parameters) 2. Call lineOpen for the deviceID of the line that is to be opened. 3. Call lineDevSpecific with a CciscoLineDevSpecificUserSetSRTPAlgorithmID message in the lpParams parameter to specify SRTP algorithm IDs. 4. Call lineDevSpecific with either CciscoLineDevSpecificPortRegistrationPerCall or CCiscoLineDevSpecificUserControlRTPStream message in the lpParams parameter.
