i want to know if i configured an E1, i must do 30 simultanous calls, the problem is i get a strange message “circuit unvailable”, instead i’ve only 30 users that call, i’m asking how can i know if all E1 channels are used or not?
I am facing alot of echo on a quintum axt 2400. I tested all other fixed gsm modules on it and there is no echo, but when i link to the quintum and place call, i hear echo. could you please advice a solution?
