Re: [OpenSIPStack] [ATLSIP] Ringing Sounds

[H.Kropf <mai...@gl...>]

Sorry

This "quick hack" method does not work, because after

void SoftPhoneSIPEndPoint::OnProgress(...)
{
  ...
  m_Manager.GetSoftPhoneInterface()->StopRingBackTone();
  ...
}

is called

void SoftPhoneSIPEndPoint::OnAlert(...)
{
  ...
  m_Manager.GetSoftPhoneInterface()->PlayRingBackTone();
  ...
}

and the RingBackTone does not interrupt


It can be necessary (for example) to add a boolean variable m_NoRingBack
in class CallSession and to use it so:

void SoftPhoneSIPEndPoint::OnProgress(
  CallSession & session,
  const SIPMessage & alerting
)
{
  ...
  if( session.GetType() == CallSession::Client )
    session->m_NoRingBack = true;
  ...
}

void SoftPhoneSIPEndPoint::OnAlert(
  CallSession & session,
  const SIPMessage & alerting
)
{
  ...
  if(!session->m_NoRingBack)
    m_Manager.GetSoftPhoneInterface()->PlayRingBackTone();

  session->m_NoRingBack = false;
...
}
