#18 How to configure Registration procedure to send 200OK directly

[praveen chebolu]

Hi,

I am trying to test our IMS stack which is deployed in multiple OEMs. Using Windows Socket APIs we are trying to do registration with OPEN IMS Server.

Issues happened so far:
1) When we send REGISTER, we are getting 401 ( AKAv1-MD5). Since we are testing in test stub where there is no SIM or eSIM module, we are sending response based on some fixed Key string password. Due to this OPEN-IMS Server keeps on sending 401 for register.
--> How can we solve this problem, is there any work-around to solve this issue?
2) We tried to disable AKAv1-MD5 and configured only Digest-MD5. But for register we are getting 403 forbidden with no matching Authorization scheme at HSS.
--> I guess P-CSCF also we need to configure with Digest-MD5 alogrithm only? If yes, how to configure P-cscf in this scenario?

Please help us to solve this registration issue..Or else help us to find a way to build the code to work directly for 200OK instead of sending 401.
