[OpenSIPStack] Help using OpenSipStack / Echo Play problem

[Christian W. <cwa...@gm...>]

Hi Ilian, 

thanks fort he hint, I have it already done and now I ran into the next
problem:

If I try to play a file which is in the format g711 alaw by calling

pDestStream->WriteData(pData, dwWrite, nRead);

the function immediately returns and if I do this without waiting some 
time before I send the next buffer I hear a short noise then nothing...

If I wait the playing is interrupted how can I get it the the playing 
sounds normal ?


Btw:

Is it normal that I hear an echo if the medaipatch was created ?
If I don’t create the path, I only get the source stream but no
Destination stream...



Kind regards 


Christian

SIP call

Hi,

Since you won't use the PC sound system, the modifications for what you 
need are not trivial.

First, you need to re-enable the following lines in SoftPhone.cxx:

AddRouteEntry("pc:.*  = sip:<da>");
AddRouteEntry("sip:.*  = pc:<da>");

These sets the linkages of  the endpoints. In this case, 
SIP-to-PCsoundsystem and PCsoundsystem-to-SIP.

Then you will have to override OpalEndPoint and OpalConnection. You can 
use OpalPCSSEndpoint and OpalPCSSConnection as reference. But instead of 
using OpalAudioStream, your classes will need to use a specialized 
OpalMediaStream that can read from your source and write any incoming 
data.  OpalFileMediaStream will probably suffice if you play and record 
from files.  To get a grasp of how the process works, try setting up 
break points in OpalPCSSEndpoint, OpalPCSSConnection , and OpalMediaStream.
