I have been tryinf for the last 5 hours to make the b410p with dahdi
Use a german isdn anlagenanschluss.
Could someone post a working
/etc/dahdi/system.conf
And
/etc/asterisk/chan_dahdi.conf?
Thank you so much
Wonder
As I only had my cell-phone to post the thread-starter, now the whole thing in more detail…
Hi,
I can’t make the B410P work with a german ISDN Line.
We have got 4 ISDN-Lines. 1 “Mehrgeräteanschluss” 3 “Anlagenanschluss”.
In case you don’t know what that is,
MEHRGERAETEanschluss gives you multiple Numbers for one ISDN Line
like 123456-1 123456-2 123456-3 123456-4 and so on… You can attach ISDN-Phones directly to that kind of line.
ANLAGENANSCHLUSS
gives you one large number-block that can span over multiple ISDN Lines.
like 123456-1 … 123456-99. You can’t atatch an ISDN-phone to that kind of line, it only works with PBXes
As I found out so far the kind of line is chosen by the signaling option in /etc/asterisk/chan-dahdi.conf.
Valid settings might be bri_cpe, bri_cpe_ptmp and bri_net
The “Mehrgeräteanschluss” actually works fine, but i can’t make the 3 “Anlagenanschluss” work.
What i did:
- Set all 4 Ports on the card to TE mode
- ran dahdi_genconf
- left /etc/dahdi/system.conf unmodified
- copied values from the auto-generated /etc/asterisk/dahdi-channels.conf into /etc/asterisk/chan-dahdi.conf
added a few options and assigned groups. As I am not at the customer any more at the moment, I can’t provide you with the exact config, but
this is my config for 1 of the ANLAGENANSCHLUSS spans:
group=2
context=in
switchtype=euroisdn
signalling=bri_cpe
echocancel=yes
overlapdial=yes
channel => 4-5
When i try to dial out on that span i just get
"unable to create channel of type dahdi cause 34 circuit channel congestion" in the asterisk CLI
when i try to dial the number of the ANLAGENANSCHLUSS from my cell, i just hear the congestion sound,
nothing happens on the asterisk CLI with Verbosity set to 100.
Can you provide me with a correct exampe /etc/dahdi/system.conf and /etc/asterisk/chan_dahdi.conf
for my setup?
Can you explain when i would use signalling method bri_cpe, bri_cpe_ptmp or bri_net?
I wasn’t able to find any official documentation on that.
I read that DAHDI now officialy supports the B410P so i didn’t install mISDN oder CAPI or other middleware.
Thanks a lot…

After all it was just problems with the telco.
