Dear All

I am willing to try Kamailio as IMS. before i try i would like to know following points

in Kamailio i see diameter support and authentication I-CSCF, P-CSCF, S-CSCF charging, QOS, ISC implemented but what about TAS do i need TAS seperately
I see that there is HOW-TO wiki , in how to wiki you are using FHoSS as HSS , can we use commercial/any other hss (afaik its using diameter so any HSS will do)?
Is there any configuration online available kamailio as IMS?
Are all IMS modules of Kamailio can be installed on one server or need each module on same machine (i am using IMS only for testing 1 or 2 calls at a time)
