[asterisk-users] ISDN Cause Code 47 Errors

We fairly recently switched service providers for our 4 PRI circuits. Since
that time, we started to notice some failed inbound calls. These calls
terminate with an ISDN cause code 47 'resource unavailble'. Most of the
time I see this error on the first or second channel on the second span in
a trunk group (This is the providers trunk group for hunting, not an
Asterisk trunk group). All the PRIs are setup as individual spans, we are
not using NFAS. If the provider sets the hunt method to 'least recently
used channel', then I can receive calls on other channels on the secondary
span, it is just the first 2 that consistently fail.
We have had occasion where the error occurs on first span. If enough calls
come in at the same time, callers who happen to land on channel 3 or above
are OK. When the problem happens on the first span, if we physically
disconnect the first span(RED alarm), the calls hunt to the second span and
all calls seem to process properly. The only way to clear the cause 47
errors from the first span is a power cycle on the provider equipment.
Power cycling my equipment does not solve the problem, only when I cycle
their equipment.
The provider says the cause 47 is coming from my equipment, yet the 'core
set debug on' log, unless I am reading it wrong, says it is coming from
their side.
I have a second server as a backup. Both servers have identical hardware
and software. When switching to the backup server, the problem remains.
I had the same setup on the previous provider, except using NFAS, and did
not have this problem.
Am I reading the log correctly?
Do I have something setup incorrectly?
Is there any way to get even lower level debugging on the PRI?
Has anyone ever had this problem and if so what was done to resolve it?
Thanks in advance for any insight,
Dale
=============
general config info
=============
There are two trunk groups for hunting by the provider TG1 = spans 2 and
4, TG2 = spans 1 and 3
I have two dual port cards in the server. Each card has 1 span from each TG
so the lost of a card will keep the other span operational. The provider
does the same across VWIC cards.
The spans do NOT use NFAS.
==================
My equipment/software:
==================
2x Digium TE210 dual T1/E1 with hw echo canceler and timing cable installed.
Asterisk 1.8.12
dahdi 2.5.0.1
libpri 1.4.12
==============
Provider equipment:
==============
Cisco 2821 with 2 VWIC2- at MFT-T1/E1
