RvSipSubsReferNotifyReadyEv() Callback Implementation
The following sample code is an implementation of the Notify-Ready event
callback. The sample demonstrates how to create, initialize and send a NOTIFY
request to the REFER initiator. This sample also checks the supplied reason, and
sets the NOTIFY parameters accordingly.
For example, if the reason is 1XX_RESPONSE_MSG_RCVD, the NOTIFY
request should include the following Subscription-State header:
“
Subscription-State: active;expires=50” and a message body that
includes the response code.
