I took a look in the TransactionClient.java and in the onReceivedMessage() method, after receiving the 401 message, it doesn't seems to follow up to return the challenge to the IMS Core for the REGISTRATION... May i asked if this part has been implemented (i.e. the returning of the authorization parameters, e.g. user name, password, nonce etc..) Joseph Hi Arjun,

Does it work? @Laurent, have you tried downloading our test client and testing your version against Open IMS and our client ? Does it work?

It does not respond with 200OK on receiving PRACK. Please let me know if I used the right version. Regards Ruchir Hi Laurent,

CSCF address can be the hostname provided the DNS is able to recognise it. In case there is no DNS mapping for the hostname, the exact IP address would need to be mentioned. @JoeTeo – we only tested with MD5.

Many Thanks! Joe Hi,

Currently "Supported: 100rel" is supported in the initial request. This is to allow the call to go through even if the UAS does not support reliable responses. When we tested with header "Require: 100rel", IMS communicator responded with 1xx without Require header and Mercuro (Bronze) responded with 420 Bad Extension. Regards Ruchir Hi Laurent
