Hi, astbox
I have the ATA HT-503 of granstream model.
How can I configure for PSTN Trunk connection in here to bind to existing PSTN Telephone Line No like 603-22271119 using above screen capture from HT503 FXO settings?
My objective I want to place calls from Asterisk —> to this existing analog PSTN Line No.
How this working in my case?
