[Asterisk-Dev] Re: [Openh323gk-users] SIP to SIP calls authenticating through a GK(gnugk)

[pesb]

Hi Nir,

       I have the following scenario:


                --------------
		|  gnugk  |
		|    GK    |
		--------------
		/	\
--------------/		  -------------
|             |           |   GW    |
|     *       |		 |  H323  |
--------------		 --------------
       /\
     /    \
   SIP   \
  Phone \
           SIP
           Phone

Because, all my system's authentication and billing procedures are inside my 
GK, I need that SIP calls to authenticate through the GK.
I hope this would clear out your doubts.

greetings,
               Pablo Salinas
