Re: [OpenSIPStack] STUN support bug?

[H.Kropf <mai...@gl...>]

Hi
I could not force STUN-client to work correctly

It is necessary :
1. Check NAT presence and Nat type
2. If Nat type is ConeNat, in that case it is necessary to enable STUN 
support
3. If Nat type is other, in that case it is necessary to disable STUN 
support

How to make it?

I have tried to use such method:

in

SoftPhoneManager::InitializeSIP()  function


before

    m_SIPEndPoint->GetProfile().GetTransportProfile().EnableUDP( 
sipIface, sipPort );


this piece of code has been inserted

if( SetSTUNServer("stun.mysrv.com") !=  NAT::SIPSTUNClient::ConeNat )   SetSTUNServer("");

and... nothing...

NAT type is SymmetricNat,  (for ConeNat it work correctly) 

The call of function SetSTUNServer("") destroys object SIPTransportManager::m_STUNClient and
object OpalManager::stun

but OSS for some reason remembers (where? how?) NAT address after SetSTUNServer("stun.mysrv.com") 
and inserts it into fields of REGISTER requests

Via: SIP/2.0/UDP [NAT IP-address]:5060;....  
Contact: "100008" <sip:100008@[NAT IP-address]:5060;......



Tell me please how to solve a problem using only OSS, without other libraries?
