Hi Alex,

Are they doing anything on inbound for you, and have you made any decisions about how you will display the tag to your customers? I have been focusing on the outbound piece of this, just starting to think about what to do with the incoming data...

Cheers,

Hi Greg.  In our use case, we purchase DIDs from them.  So, they are the inbound carrier (they are a CLEC and IPES) and STIR/SHAKEN Service Provider.  However, we do not use them for termination.  They offer service termination, but we do not use them due to existing contracts.  So, in order to have our calls signed, we needed them to do it.  The biggest issue we've come across is the number of companies /able to /provide this service is limited, especially to the Asterisk community. I stress able to because even though some companies are Service Providers, they are simply not technically capable of offering it.

I will send you my contact's information at TILTX privately.  He's a subject-matter expert with the STIR/SHAKEN framework and he's offered us invaluable help.

Thanks,
Alex

    I wonder if you could step back and explain the big picture, as
    I'm not
    really following this.   As I understand it:

      usually asterisk is used as a pbx

      STIR/SHAKEN is a protocol run between carriers to prove the
    authority
      to use the claimed callerid

      when someone gets service from a carrier and connects to it from
      asterisk, I would expect the carrier to basically filter the claimed
      callerid to be from the set of values recorded with your account as
      legit, and for the carrier to do the STIR/SHAKEN authentication.

    So I wonder if your asterisk instance is connecting to the PSTN as a
    top-level carrier, or, more likely, I am confused in some way.
