[SR-Users] P-CSCF without Rx interface

[Mojtaba]

Hi,
The answer is right,

About your question: "I'm not able to find how to tell P-CSCF where to
direct the sip traffic. It obviously should happen in
route[REGISTER]."

In [REGISTER] route block you could see this line:
$ru = "sip:"+$rU+"@"+$rd;
Actually you are setting R-URI, In this line the $rd PV refer to ICSCF
in IMS network.
With Regards. Mojtaba
