Holy Cow. :)
Is there a patch for this ? Has a bug report been raised ? I couldn't
find any ....
Is there any work around for this until the bug is fixed ? Is it the
"Restarting Channels" that is aggravating the situation - I think that
there is an option to specify the restart timeout. I do restart asterisk
every night, so would it be possible to disable the restart of the B
channels.
Sorry for soooo many questions, but this is a real "bum-biter" !!

Hi,
that is a bug in libpri. You will sometimes notice a message like:
!! No channel map, no channel, and no ds1? What am I supposed to
identify?
This is caused by a restart message from the switch containing no
channel ident IE. According to the ETSI standard this indicates a
restart of all B channels on that span. Libpri just ignores this
message. Now all B channels are "blocked" for incoming calls.
You can free them by making outgoing calls.
Fixed in BRIstuff since May. ;)
best regards
Klaus

We've got a EuroISDN (32 channels) with a TE405p, running cvs head as of
5 days ago.
In the past couple of days, we've hit a scenario where incoming calls to
the * pbx from the PSTN are being marked as busy, but outgoing calls
work just fine. When we reboot *, the problem goes away. Has anyone else
had this ? I've attached a PRI debug below. I've changed the phone
numbers (x & y) to protect the innocent :)
Please tell me that there is someone who has had this issue, and knows
how to get round it. It's making my users, well, irate ...
Many thanks.
