Busy/congestion

15 years 7 months ago #1984 by pastore
Hi,

go to the asterisk CLI (asterisk -r) and post the output of the "misdn show stacks" command. There is a number of reasons why you obtain a congestion tone. Anyway your bri connections are down, in fact the leds on the card blink only when connection is down on layer 1/layer 2.

As I thought...L1 and L2 are both down: this means that BRI connection is absent also at the lowest level, the electric one. In this way a call is simply impossible, because your card doesn't see anything attached...the possibilities are: your card is fisically damaged, the wires in the rj-45 plug are put in a wrong way, the device attached to the card is damaged/not well configured. Is this last one another pbx or a pstn-box?
