Re: [reSIProcate-users] [TP-SPAM] - How to got multiple connections ip from SDP ? - Email found in subject

There is only ever a maximum of one connection specified at the session level (sdpContent->session().connection().getAddress() extracts this).
However there may also be optionally connections specified per medium. To obtain these connections/addresses you need to iterate through the mediums:
 
// get session level connection
const Data& sessionAddress = sdpContent->session().connection().getAddress();
 
// now iterate through mediums
 
const list<SdpContents::Session::Medium>& mediums = sdpContent->session().media();
for (list<SdpContents::Session::Medium>::const_iterator m=mediums.begin(); m!=mediums.end(); m++)
{
   const list<SdpContents::Session::Connection>& mediumConnections = (*m).getMediumConnections();
 
   for (list<SdpContents::Session::Connection>::const_iterator mc=mediumConnections.begin(); mc!=mediumConnections.end(); mc++)
   {
      const Data& mediumAddress = (*mc).getAddress();
      ..
   }
 }

Hi all, in the statck/test/testsdp.cxx, there has :

      Data txt("v=0\r\n"
               "o=CiscoSystemsSIP-GW-UserAgent 4316 2064 IN IP4 65.39.205.114\r\n"
               "s=SIP Call\r\n"
               "c=IN IP4 65.39.205.114\r\n"
               "t=0 0\r\n"
               "m=audio 36928 RTP/AVP 0\r\n"
               "c=IN IP4 65.39.205.114\r\n"
               "a=rtpmap:0 PCMU/8000\r\n"
               "m=video 36924 RTP/AVP\r\n"
               "c=IN IP4 65.39.205.114\r\n");


This SDP has two c= lines, how to parse it to got these two c= line IP ?

I just saw sdpContent->session().connection().getAddress();

Thanks
