Thanks for the reply I want to use Kamailio as a proxy, but a *smart one*. It doesn't store anything, but: • Modifies REGISTER requests → adds the client's IP/port to Contact • So when the PBX sends an INVITE back, Kamailio reads this data from the R-URI and forwards the call to the client
Hope it makes sense.
