I am running freepbx distro 4.211.64-9 witch 2x Sangoma A101 PRI card conected to E1 line.
Spec for E1 line from teleco (Netia - Poland):
Framing/Coding: CSS/HDB3 witch CRC4
Signalling: Pri - CPE
I have no alarms on dahdi and spans are up, but after few sec I got message :
[2013-12-10 11:43:02] WARNING: sig_pri.c:7276 pri_dchannel: PRI Error on span 1: Received MDL/TEI managemement message, but configured for mode other than PTMP!
After trying make call i got message that span go down :
[2013-12-10 11:43:08] WARNING: sig_pri.c:1150 pri_find_dchan: Span 1: D-channel is down!
Teleco say that on client site was something look like logical loop.
On Freepbx distro 1.811.210.57-1 with this same card config everything works fine
