[SR-Users] Facing issue in Registration of SIP Client

[sainath.ellendula at wipro.com]

Hi Franz,

Thanks for your response.

Now, SIP Client is Registered with Xlite softphone and call has been established between SIP Client(X-lite) and IMS Client(Boghe).

Now I was trying to configure Hard phone same as SIP Client configurations to make a call between soft phone and hard phone. Configured everything on hard phone but have to Disable NAT.

Could you please help me, where to DISABLE NAT in configuration file.

Thanks in advance!!

Regards,
Sainath

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.
