[cisco-voip] Cisco Cube drops uri-user in From header with no reason

[daniele visaggio]

Hi list,

Weird issue on ISR4331/K9 running isr4300-universalk9.16.03.06.SPA.bin.

Given that, cube has two interfaces, inbound and outbound.

Given that there are no voice translation rules and there are no voice
class sip-profiles, how is it possible that cube is dropping the uri-user??

Has anyone seen this kind of behavior?

Thank you
