Hi, You're right about using IP Auth in Kamailio. You'll need to use the permissions module. However I believe permissions module wont send the OPTIONS to the MSC SIP Server. For this you may alternatively use the "dispatcher" module.
Take a look at the sample kamailio.cfg here: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb Follow the tag WITH_IPAUTH and I'm sure you'll be able to implement it easily.
