[reSIProcate] Does there have a common way to got RFC headers value	and extension headers value ?
Hi, I want to write a function to got the headers value. it's working fine with Extension header, but for the 
RFC header, likes contact, to, from. I got assert error,.
How to mofify this function then it can be working with 
RFC headers and extension headers both?
 
Thank you in advance.
 
 
void GetHeaderValue(Data buff, string headerName)
{
 SipMessage * message = SipMessage::make(buff);
 if (!message)
 {
  return ;
 }
 ExtensionHeader h_Extension(headerName.c_str());
 if (message->exists(h_Extension) == false)
 {
  return ;
 }
 if (message->header(h_Extension).empty() == true)
 {
  return ;
 }
 if (message->header(h_Extension).front().isWellFormed() == false)
 {
  return ;
 }
 Data temp(message->header(h_Extension).front().value());
 
 
 
}
