How to set up a bunch of D-Link DVG 7111S and Asterisk?

Question

linux

Good day, I ran into a problem connecting an analog external line to Asterisk using an FXO gateway. Tried both through extension and through various options for trunks, changed settings and firmware on the gateway, nothing helps.

Available:

• Analog line from the operator Intek (Convex) in Yekaterinburg
  
• D-Link DVG 7111S gateway (1 FXS + 1 FXO)
  
• Asterisk 13 + FreePBX
  

I have suspicions that Asterisk has nothing to do with it. it works with IP handsets and another GrandStream GXW4224 (24 FXS) gateway perfectly.
