My E1 has 10 lines from my telco, 10 lines are blocked and 20 are idle.
I guess those 10 blocked are my lines(channels). Also reading this:
http://voip-info.org/tiki-index.php?page=Asterisk+MFC+R2
i come to this lines:
"...
cas=110-124:1101
The 4 characters after the colon in the cas statements define the idle
patternfor the signalling bits. For China and Thailand you should use
1111 instead of 1101. 1101 should be correct for all other countries
using MFC/R2. This pattern puts the trunk in the blocked state, so when
no application software is using the trunk it behaves in a sensible way.
(...)
You should get a green light. If you make calls into the E1 you
find the E1 is blocked. This is the correct state before asterisk is
started."
I use 1101, that should be correct, and it should be correct to have 10
lines blocked, 1 to 10. It is also correct that those 10 lines are
blocked _before_ asterisk is started. But the problem is that asterisk
says those lines are still blocked when i try to simulate a call.
Using libunicall-0.0.2's testcall executable i get this output, and as
you can see initialli y have 10 blocked lines :-(, errors from line 11
to 31 (i only have 10 lines) and then messages of "local end unblocked!"
for each of the 31 lines.
