Lawful Intercept only for ingress calls
Hello Community,
My customer asks whether it is possible to tap only incoming (ingress) calls and no outgoing calls (egress) on a specific realm. Customer will be using LI based on X1/X2/X3.
For ingress calls tapping should be both on the From and To headers
In the documentation I read about x2-sip-header-orig, x2-sip-header-term, x2-sip-header-redir and x2-sip-header-match. I read that on ingress the Net-Net SCB uses x2-sip-header-orig and on egress it uses x2-sip-header-term and x2-sip-header-redir.
If I configure these parameters like below, will that trigger LI tapping only on incoming calls?
- x2-sip-header-orig "from request-uri to"
