Hi Joegen:
=20
I don't have a call sesion, i have a proxy session. The cancel is sent to t=
he m_DialogPeerAddress for a proxy session. I have added the following code=
:
=20
void ProxySession::OnDNSFailOver(
SIPDNSFailOver & failOverEvent
)
{
SIPMessage msg =3D failOverEvent.GetMessage();
if( msg.IsInvite() )
{
SIPURI targetURI;
msg.GetRequestURI(targetURI);
SetDialogPeerAddress( targetURI.AsString() );
}
}
=20
Then the cancel is sent to the actual target of the ICT transaction, but if=
the actual target is not answering, the ICT continue trying with the actua=
l target and with the followings. The ICT transaction must stop trying. Cou=
ld you give some directions, please?
Thanks for your help.Gustavo.=20
