Can you show me your trace and tell me, what you've provisioned in the HSS? Are you using Fraunhofer's HSS?

You should have an IMPI as well as an associated IMPU like this: &quot;09876993998754(a)IMS1.NET1&quot; We've tested Kamailio with a whole bunch of HSS's (from NSN, E///, ZTE, SummaNetworks, ...), so it's definitely not an issue on Kamailio. Huawei should work straight away.
