Guide needed: Asterisk → Yeastar TE100 (PRI) when I only know direct SIP trunks

I’m comfortable setting up Asterisk with a direct SIP trunk to an ITSP, but I’ve never used a Yeastar TE100 PRI gateway in between. I need guidance on the right way to connect Asterisk ↔ TE100 ↔ PRI.

Concept I think is correct:

Endpoints (SIP/WebRTC) ⇄ Asterisk ⇄ SIP/IP peer trunk (no REGISTER) ⇄ Yeastar TE100 ⇄ E1/PRI ⇄ Telcom


someone please walk me through best practice

if possible can anyone share documentation

How about to try Yeastar documentation and support?

Does it have to be via a VoIP gateway? There are (or were) ISDN PRI cards available that work with the chan_dahdi driver directly from Asterisk.
