OK I found the (old) notification code.
In the flowgraph we have:
UtlBoolean MpCallFlowGraph::handleSetDtmfNotify(MpFlowGraphMsg& rMsg)
{
OsNotification* pNotify = (OsNotification*) rMsg.getPtr1();
MpConnectionID connId = rMsg.getInt1();
return mpInputConnections[connId]->handleSetDtmfNotify(pNotify);
}
I could change the return line to:
return mpInputConnections[connId]->handleSetDtmfNotify(pNotify) &
mpDecodeInBandDtmf[connId]->handleSetDtmfNotify(pNotify)
Then in DecodeInBandDtmf::handleSetDtmfNotify() I save the pNotify pointer,
then I could try to notify using a similar code as in MpdPtAvt:
if( mpNotify != NULL )
mpNotify->signal(0x80000000 | (0x3fff0000 & (mCurrentToneKey << 16)));
However, it won't be possible from the application point of view to know if
it's a RFC2833 DTMF or INBAND DTMF (as I would use the same Notification
object as MpdPtAvt).
I'm now going to see how I can add a second Notification (dedicated to
INBAND dtmf)... but I fear this would require many changes.
