AddSecurityParamsL(TSIPTransportParams &, CSIPRequest &, TRegistrationId, TTransactionId, TInetAddr &, const TDesC8 &, const CUri8 &, const TDesC8 &, MSIPSecUser &)

void	AddSecurityParamsL	(	TSIPTransportParams &	aTransportParams,

			MSIPSecUser &	aUser
		)

Adds the cached security parameters to the SIP request. If no cache entries are found returns without any error.

Parameters

TSIPTransportParams & aTransportParams	params to be used when creating IPSec SAs. If an SA was created on return contains also the updated transport identifier.
CSIPRequest & aRequest	SIP request where the security parameters will be added
TRegistrationId aRegistrationId	Registration ID
TTransactionId aTransactionId	transaction ID
TInetAddr & aNextHopAddr	the next hop IP address of the request
const TDesC8 & aNextHop	the next hop of the request IP address or a domain name
const CUri8 & aRemoteTarget	Remote target of the request
const TDesC8 & aOutboundProxy	the outbound proxy of the request IP address or a domain name. Zero-length if not present.
MSIPSecUser & aUser	the user for the possible cache entries
