Hello,
I have an issue regarding the last asterisk with dahdi that I installed.
The big picture: one server with 1 digium card TE405P (2nd Gen) and the next ISDN connections:
PBX TELCO ---- 2 x ISDN -----span 1 & 2------------
|
Mediant Audiocodes 1 ----- 1 x ISDN - span 3---- PBX -Asterisk 1.8.32 + dahdi 2.10.1
|
Mediant Audiocodes 2 ----- 1 x ISDN - span 4------
I have the following configuration:
dahdi/system.conf
span=1,1,0,ccs,hdb3,crc4
span=2,2,0,ccs,hdb3,crc4
span=3,0,0,ccs,hdb3,crc4
span=4,0,0,ccs,hdb3,crc4
bchan=1-15,17-31
dchan=16
bchan=32-46,48-62
dchan=47
bchan=63-77,79-93
dchan=78
bchan=94-108,110-124
dchan=109

channel => 63-77,79-93
group = 4
context=from_mdk
switchtype = euroisdn
signalling = pri_net
channel => 94-108,110-124
All the spans are up, but from time to time span1 and span 2, connection with PBX TELCO become down from a few seconds than up again.
== Primary D-Channel on span 2 down
[Jun 15 09:13:31] WARNING[18343]: sig_pri.c:1127 pri_find_dchan: Span 2: D-channel is down!
== Primary D-Channel on span 2 up
On cli I see this message:
PRI Span: 2 TEI=0 MDL-ERROR (A): Got supervisory frame with F=1 in state 7(Multi-frame established)
PRI Span: 1 TEI=0 MDL-ERROR (A): Got supervisory frame with F=1 in state 7(Multi-frame established)
Can somebody tell me what is the problem ?
Before this instalation the digium card was in another server with asterisk 1.8 and an older version of dahdi 2.6, but i didn’t have this issue.
In paralel with this new sever I have another server with asterisk 1.8 an older version of dahdi 2.6, with the same connections and I don’t have this issue.
Thank you.
