[SR-Users] I-cscf module not reading correctly UserAuthenticationAnswer

[Gennaro Sarnataro]

Hello everyone,
I'm using kamailio modules as Interrogating-cscf and Serving-cscf.
Registering an user i perform correctly an UAR and the HSS answers
correctly with an UAA giving user'c server-capabilities.

Even if i have a success result code ( as you can see in the attached
wireshark dump) the configuration code bring me in the failure branch.

 route[REG_UAR_REPLY]

as you can see from my log i think tre's some problem when
reading UserAuthenticationAnswer return code.
