on UCM62xx unfortunately Zero Config allows you to configure the FXS part of HT-813 but not the FXO part. On the contrary, it is misleading because it sees 2 FXS,
other than that I can not in any way record FXO of HT-813 SU ucm, can someone kindly give me a hand step by step?
(I’ve never seen an FXO before)
I’ve read the manuals but they’re very vague.
