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.

Hi, We have a requirement with one of our telco We are using asterisk in our servers and we are planning to implement SIP-I protocol and we choosed kamailio for it.
In Kamailio website, i came to know that kamailio will be supporting both SIP-I and SIP-T protocols
Below is what we need and pls confirm whether it is possible or not?
Asterisk PBX <-------> Kamailio <--------> Telco MSC
Telco will be forwarding the calls to kamailio on sip-i protocol and kamailio server has to forward the calls to our Asterisk server by converting sip-i to standard sip protocol
Similiarly Asterisk will be initiating sip call to kamailio server and kamailio server should convert it into SIP-I and should forward the call to Telco MSC
- I am able to establish the SIP trunk [sending OPTIONS from asterisk
and kamailio acknowledges with 200 OK] between Asterisk and Kamailio using dispatcher module in kamailio and sip.conf in asterisk.
How to establish the SIP trunk between kamailio and telco MSC? [Generally MSC will act as SIP server and kamalio should send OPTIONS packet and MSC will acknowledges with 200 OK]
My telco MSC has only provided me the MSC SIP IP and there were no username/passwords provided. Means i need to use IP based authentication for the SIP Trunk establishment.
In Kamailio how to achieve it?
Please help and any suggestions/feedback will be highly appreciated and thankful
