Hi,
We are trying to integrate Asterisk PBX with the openIMS setup. The Asterisk in this case will behave as an AS. The problem that we are facing is as follows:
While registering with IMS, a Third Party registration is also to be done with the PBX. While doing so, after receiving the register message, PBX sends back a 401 unauthorised message to the S-CSCF. As per IMS standards, S-CSCF is not supposed to respond to any such message from any AS. It only expects a 200 ok.
Please let me know how the authentication procedure at Asterisk can be turned off.
