Hello Nils,
Attached is the mentioned files you asked me to send. As you said, after disabling gnutls in configure, I can compile it. It works fine . Thanks for your kind help.
One important question I would like to ask you.
Suppose I am having 100 SIP clients, all of them are behind their respective 100 NAT's, The NAT devices are assigned public IP dynamically. What besides openser do I need on my SIP server to traverse those NAT's. Assume NAT's does not support STUN. Do I need to put STUN or Mediaproxy/RTPProxy server on my SIP server. If not , then how could i can manage such network.
Thanks a lot for your kind help
Best Regards
Lokesh

Hello Lokesh,
could you do me a favor and send me config.h and config.log from the
directory
where you tried to compile 0.9.2?
After you send me the files you could try the following command './configure --disable-gnutls' and afterwards 'make'. I think that should
help
to compile sipsak-0.9.2 on your system.
Thanks Nils

But there is no such problem with 0.9.0 version.

I would really appreciate it if you could describe we what problems
you
had
with sipsak 0.9.2. Then I could try to fix it, if it is a bug in
sipsak.
Thanks Nils
Hi Lokesh!
First you install a STUN server. Then, the clients use this STUN server to detect the kind of NAT. If the detected NAT can be traversed by STUN, then they use the public_IP:public:port in the SIP messages. Thus, the sip proxy can not (need not) differ between clients with public IP and clients with NAT+STUN.
If the NAT can't be traversed by STUN or the client does not support STUN, then the SIP proxy should take care of it. You can use the functions of the nathelper module to: 1. detect if the client is behind nat 2. to rewrite the SIP message 3. to force an RTP relay (rtpproxy)
instead of nathelper+rtpproxy you can also use mediaproxy module + mediaproxy from ag-projects.
