enableSessionTimer method
Enables SIP session timers (RFC 4028) for subsequent calls so the server reaps a dead leg at expiry when the client stops refreshing.
Parameters:
timerSeconds: Session interval in seconds (minimum 90).refreshMode: 0 = UAC (caller) refreshes, 1 = UAS (callee).
Returns 0 on success, negative error code on failure.
Implementation
Future<int> enableSessionTimer({
int timerSeconds = 90,
int refreshMode = 0,
}) async {
throw UnimplementedError('enableSessionTimer has not been implemented.');
}
