1. A method of managing an IP call between a calling party and a called party, the method comprising:
- receiving, at an interceptor, a first request to set up the call forwarded from the calling party through a gateway;
terminating the first request at the interceptor;
generating a second request at the interceptor to set up a call between the interceptor and the called party;
setting up a first IP call session between the interceptor and the called party in response to the second request;
setting up a second IP call session between the interceptor and the calling party in response to the first request;
operating the interceptor to forward information received from the called party during the first IP call session to the calling party through the second IP call session, and to forward information received from the calling party during the second IP call session to the called party through the first IP call session; and
operating the interceptor to record SIP communications and IP call session packets received from the first IP call session, and to record SIP communications and IP call session packets received from the second IP call session.

9. An IP network for managing an IP call between a calling party and a called party, the IP network comprising a gateway and an interceptor, wherein the IP network is arranged to:
-
receive, at the gateway, a first request to set up the call from the calling party; determine, from the first request, a requirement to route the call through the interceptor; forward the first request from the gateway to the interceptor and terminate the first request at the interceptor; generate a second request at the interceptor to set up a call between the interceptor and the called party; set up a first IP call session between the interceptor and the called party in response to the second request; set up a second IP call session between the interceptor and the calling party in response to the first request; operate the interceptor to forward information received from the called party during the first IP call session to the calling party through the second IP call session, and to forward information received from the calling party during the second IP call session to the called party through the first IP call session; and operate the interceptor to record SIP communications and IP call session packets received from the first IP call session, and to record SIP communications and IP call session packets received from the second IP call session. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
