I don't think so. Because th P-CSCF address will be mostly assigned by DHCP Option. Because when you're are moving with your device, you move from one area to another one covered by annother GGSN, which mean you'll have to contact a new P-CSCF, this without invalidating your registration. The Registrar (S-CSCF) know where to send back the requests only because it is listed in the Route/Record-Route from every request. So the P-CSCF Address is not asserted in the Service-Route in the 200 OK following a successful registration. Olivier B. Benny Prijono a ?crit : > Roland Klabunde wrote: >> Hi Benny, >> >> Hmm.
