[OpenSIPS-Users] question on B2B module

[ha do]

Hi Anca


let me describe the topology:
VOIP Service Provider --------SIP trunk port 5070----Opensips1 --sip trunk port 5060----Opensips2----Ip phone

the Opnesips1 has 2 interface :
      interface 1 : IP address 192.168.1.2 -- trunking with opensips2
      interface 2 : IP address 115.22.22.3 -- trunking with VOIP service provider
      VOIP provider IP address : 115.1.1.2 
IP address of Opensips2 : 192.168.1.3

when i do top hiding 
 
if(is_method("INVITE") && src_ip=="115.1.1.2")
   $du=192.168.1.3//is it right ?
   b2b_init_request("top hiding");
what is value i set :
modparam("b2b_entities", "server_address", "which IP address Private or Public")Thank you
Ha`

Hi Ha,

Yes, such a configuration is possible. You have to set the $du to the 
address of OpenSIPS2 before doing b2b_init on OpenSIPS1.
