New subject: [Serusers] Re: [Serdev] How to gaurd PSTN gateway with openser + NAT

18 Nov 2005

Hello Friends,

I installed openser, it is working fine. sipsak-0.9.0 is also working fine,
previously i was using 0.9.2 version of sipsak that is having problem.

Now I want to ask you 2 important things.

1>> Forget Asterisk for sometime, I am having a openser with one public IP
and one private IP, and I am having one voip gateway which is connected to
E1 PRI, and voip gateway is also having private IP. So, my question is can I
forward all the calls coming on public IP of openser to voip gateway via
private IP's of openser and voip gateway.After that voip gateway will
forward the call to E1 PRI.
SER Admin guide mentioned about how to gaurd your PSTN gateway with SER, but
the documentation is not suffciente there. So, can you please suggest in
this scenario, how do i can configure request routing in openser, like
pstn.cfg file.

2>> How do I have to register SIP phone on openser. Where the sip phones are
behind the NAT, but NAT device supports STUN and UPnP. Do I need to setup
seperate STUN server or I can run this service on openser server.

Please help.
Regards
Lokesh

  Hi Lokesh !

 here i am writing my own experience baed views and facts: -

 1) openser i certainly better than ser with better nat handling tricks, it
 also has got TLS support first time ina sip server and certain other
 enhanced feature are alo there, that can be find out on www.voip-info.org

 2)sipsak is working fine on my pc and i really had no problem in installing
...
  it, i have installed vesion sipsak-0.9.0

 3) i have not istalled any ser administrative program, so i can't tell you
 which one is better.

 4) in case of Radius server try with radius 0.9.0.

 5) Finally, ser doesn't have any pstn support so you can't connect it to
the
...
  pstn gateway,
 you can forward all sip packets to asterisk server and it would forward it
 to pstn gateway and i think that's is the possible solution of your problem.
...

 regards,

 Deepak
