I see, that makes sense. So then I have two follow-up questions:
1. If you are connected to multiple carriers, e.g. multiple long
distance carriers, how do you populate your routing table? (Obviously "it
depends" but I'd be interested to hear an example.)
2. If you are setting up

way. You would look at your usual LCR/routing table, and the adjacent switch

Hi all,
I'm trying to understand how routing works in SS7-land. I am familiar with
portability, and I know (at least in the US) the first step in routing a
call is doing an LNP dip to get the LRN.
However, it looks like addresses in MTP3 are "point codes" (PCs) which are
assigned to switches.
So far this trail of emails is correct. All calls have to be traceable back to
the origination provider (via PA registered certificates) for legal enforcement
purposes. So each SP will need to authenticate (guarantee validity of) their
own calls. You just don’t necessarily need access to your
Replace “robocalls” with “spoofed calls” and you would be correct. A service
provider can legitimately provide A attestation to calls that turn out to be
illegal robocalls, as long as the caller can legitimately use the number they
are calling from. At that point the traceback functionality
Exactly that. The idea is collateral pain for misbehavior. Or attorneys
general knocking on doors wondering why they're allowing robocalls

Thank you, that’s very clear and sums it all up!
One lingering question: even without providing a fully attestable chain of

Pretty much anyone provides this. I would first decide if you want to go
with an OTT (over the top) provider or ILEC/CLEC that services your
customer's location. For OTT, I have always liked Nexvortex. They have
been around a long time.

There is a STIR-SHAKEN process of registering and testing with the Policy

purchase SHAKEN token certificates from a Certificate Authority (CA) and
begin to engage in using the technology. This is not a walk in the park.

them. I have an advanced certification with them, but this sort of thing
was never covered in training, and I've never heard of it before. Our core
