SIPTransaction.cxx: In member function 'PUDPSocket* SIPTransactions::SIPTransaction::CreateUDPSocket()':
SIPTransaction.cxx:784: error: conversion from 'Tools::OString' to non-scalar type 'PIPSocket::Address' requested

I see in the file at line #784 that was wrote:

PIPSocket::Address localAddress = m_InterfaceAddress;

I change this line to

PIPSocket::Address localAddress = PIPSocket::Address(m_InterfaceAddress);

and the I dont have any error...
