I wish to cancel an outgoing call which the remote side does not answer longtime (ringin on remote side). For this purpose I should send message CANCEL. For this it is necessary to call method CallSession:: SendCancel()? But how to obtain CallSession object? Some softphones (for example EyeBeam set) announce method CANCEL in the list "Allow" of message INVITE. Why OSS does not do it? |

I am assuming you are referring to the SoftPhoneInterface module? There is no need for you to cal SendCancel() directly. Simply calling HangUpCall() will either send a BYE for mid-dialog and a CANCEL during setup stages. > Some softphones (for example EyeBeam set) announce method CANCEL in the > list "Allow" of message INVITE.

Sorry.
"Mea culpa" ::)
I casually used it
SetUpCall("pc:*", dest, SetCurrentCallToken() );
instead of
SetUpCall("pc:*", dest, m_CurrentCallToken);

Probably OpenSER does not send message CANCEL to the client at whom it
is not declared CANCEL in list "Allow" of messages REGISTER and INVITE.
The sessions rejected by the CalledStation therefore hang.

How to set custom User-Agent in SoftPhone or SoftPhoneInterface? Is it possible to use short mode of SIP-tags (f:, t: instead of From:, To:) in SoftPhone or SoftPhoneInterface? |

Hi all, I try to send G711 Alaw data on the destination media stream but it Is snatchy if the delay between the packets doesn’t match... The delay of 20ms is not always right, how can I time the packets ? I use OpalMediaStream::WriteFrame() for sending the data ... Kind regards Christian No virus found in this outgoing message.

Hi Ilian, Thanks for the response, but I don't understand where to override it ? I use the SoftPhone code to get it running and this is my last problem. The MediaStream was already created if this function BOOL SoftPhoneManager::OnOpenMediaStream(OpalConnection & connection, OpalMediaStream & stream) Is called. Do you mean, that I need to change it in OpalConnection or where should I do so ? Kind regards Christian -----Ursprüngliche Nachricht----- Von: ope...@li...

Hi, You mentioned earlier that you wanted to play to or record from a source/target other than the PC's sound system? The Softphone is using the PC sound system endpoint (i.e. OpalPCSSEndPoint) by default. But since you mentioned that your target environment may not necessarily have a mic or speaker, you will need to change that. If for example you need to play to or record from a file, you will need to create classes like OpalFileEndPoint, OpalFileConnection, and OpalFileMediaStream which are analogous to OpalPCSSEndPoint, OpalPCSSConnection, and OpalAudioMediaStream. Just to refer to the said classes and pattern your implementation to their interfaces. Then use your OpalFileEndPoint instance as as endpoint in SoftPhone.

Hi Ilian,
I already modified it, so i only use the SIPEndPoint which is derived
>From OpalOSSEndPoint.
I dont wanna play files, I get a block of i.e. 2048 bytes of g.711
Alaw data which I then need to send over the connection ...
If the SIPEndPoint got the answer the RTP will be made and for each
Direction I get a Stream. If the Stream is opened the callback
BOOL SoftPhoneManager::OnOpenMediaStream(OpalConnection & connection,
OpalMediaStream & stream)
will be called.
I store the streams inside another class and wait until both streams are
Active. If they are active I send the data (which comes from a file for
Test purpose) on the stream where IsSource() == false.
I dont know what to derive, since all functionality I need is already
There. The only one problem is the syncing of the data...
Attached you find the code I use for testing:
void someclass::StreamHandler(void)
{
//variables
///////////
OpalMediaStream *pSourceStream = NULL;
OpalMediaStream *pDestStream = NULL;
BYTE *pData = NULL;

{
pData = new BYTE[this->m_nDataSize + 10];
carray.SetAt(n, pData);

}

};
};
};
};
//if the source stream is established

nReadSize, &dwWrite, NULL) == TRUE) && (dwWrite > 0))
{
for(int n = 0; n <
dwWrite; ++n)
{
pData[n] =
bitdreher[pData[n]];
};
packet.SetPayloadSize(dwWrite);
packet.SetTimestamp(CalculateTimestamp(dwWrite, src));
packet.SetPayloadType(RTP_DataFrame::PCMA);
memcpy(packet.GetPayloadPtr(), pData, dwWrite);

Christian,
I am not sure what you meant by "The only one problem is the syncing of
the data...".
I have implemented a similar class in the past to be used UA that needs
to send file. See the implementation of the VoiceFileChannel class. It
supports RAW input from preencoded G.723.1 and G.729 File. You can use
this class as your reference and create a RAW G.711 handler. You may
then attach it to the OpalMediaStream.
HTH,
Joegen
