[OpenSIPS-Users] B2BModule and topology Hiding

[Mehdi BOUDOU]

Hello,


I'm already testing the b2bua module with the simple topology Hiding test,
with a sipp scenario of a simple call.
The Call is OK but I set the modparam("b2b_entities", "replication_mode",
0) and the call id of new leg is the same for the new INVITE ?

Thanks in advance


Here my config file :
