<br clear="all">Hi All,<br>I am having an issue with layer 2 in BRi connection configured using Misdn:<br>after
the BRI line working fine, a technician from our phone company came in
to add another number, after testing with his ISDN phone and BRI line is
working, from our asterisk server it is not :(.<br>
When I check ports with "misdn show port x" it says:<br><br>
* Port 4 Type TE Prot. PMP L2Link DOWN L1Link:UP Blocked:0 Debug:7<br>
(as you can see here L1Link=UP <b>but</b> L2Link=DOWN)<br><br>
since we didn't change any setting from our end, it maybe an change from our phone provider end that caused to have a <b>mismatch in the layer 2 connection</b>.<br>
<br>
<b>what we tried is:</b><br>
- we did reboot our phone system several times.<br>
- I did reconfigure the ISDN trunk setting to refresh things (<b>using
the same config that worked before</b>)<br>
- I did use another phone system that was not used before (to
eliminate the possibility that our current phone system has hardware
issues) with no success, it <b>displaying the same Layer 2 issue
found</b>.<br>
- I turned debugging on when making calls, it shows that calls go
through as programmed but it hits a down line (because of L2 issue)
