RE: ring-back

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We didn't do any patch, we only remove this comment character "//" to this
fusion switch (m_lastQ931->GetMessageType(case Q931: tatusMsg:
In this class:
 CallSignalSocket::ReceiveData()
And then we re-compile the code.
That is all.

Gustavo.

Gustavo,

Could you post a patch for that please?  This may solve a similar 
problem for me
