I'm working for a big telco in Europe, and I'm just marginally involved
in the telco network.
AFAIK, in our infrastructure, SS7 is a niche in some very old equipment
sitting somewhere.
On fixed broadband, we migrated everything over IP, voice is SIP,
including VAS services, that are somehow fading away as well (IMS still
in place for voicemail).
On 5G Standalone, everything is HTTP on the control plane and GTP
encapsulation on the user plane.

I'm not an expert, but I wonder if the complexity has increased the
potential attacking surface.
Cheers,
Tara
