CSIPReferDialogAssoc Class Reference

class CSIPReferDialogAssoc : public CSIPDialogAssocBase

Class for managing SIP REFER dialog associations. It provides services for creating, using and terminating SIP REFER dialog associations. User can have multiple REFER dialog associations per same SIP dialog. Implementation handles SUBSCRIBE on the dialog level defined by Call-Id, local and remote tags; User is responsible for "Refer-to" header semantics. sipclient.lib
