Hi, the X-Lite is a normal Sip Client .. for IMS registration you need an IMS client .. such as Boghe based upon doubango. You are only able to use normal username/password register while using X-Lite Cheers, Fred Am 18.02.2016 um 11:53 schrieb sainath.ellendula@wipro.com<mailto:sainath.ellendula@wipro.com>: Hi Franz, Thanks for your response.

Please find the attached traces and let me know any more changes has to done. Thanks in advance!!

It uses the public identity “sip:bob%40net1.test@net1.test”. I don’t think that such a user has been provisioned in HSS. The diameter UAA request (packet #436) also clearly says: AVP: DIAMETER_ERROR_USER_UNKNOWN.

Therefore you must adapt the authentication for the user (bob) in HSS accordingly and set in the default authentication algorithm in the parameter-file scscf.cfg to "HSS-selected" (define REG_AUTH_DEFAULT_ALG "HSS-Selected").

Hi Sainath, "Digest- observed as Please look into the tracefile. The Diameter MAR in packet#18 contains AVP: SIP-Authentication-Scheme(608) l=28 f=VM- vnd=TGPP val=Digest-AKAv1-MD5 which leads to " HSS Authentication Scheme Unsupported", because HSS now expects to challenge with Digest-MD5. That means that the S-CSCF still uses "AKAv1-MD5" as default authentication schema. You should change/enable REG_AUTH_DEFAULT_ALG "MD5" in scscf.cfg or - as a better alternative - use "HSS-Selected". Then try again. BR Franz

Hi, NAT is handled by P-CSCF. The are two switches in pcscf.cfg which must be set "off" as shown: ##!define WITH_NAT ##!define WITH_NATPING That's it. BR Franz
