How to install a card B100P on Elastix 2.0.3 ?

Earlier I used mISDN driver, but with Elastix I'm using default DAHDI driver with B400P...
After installing Elastix, all I did is go to Hardware Detection - Detect New Hardware and car is configured.

As far as I can see, your card is recognized by Elastix..in my experience .aprox. 90% of problems with ISDN is related to hardware or telco...
Try changing cable connecting B400P and ISDN equipment (I'm using UTP Cat5e cable), change NTU (ISDN Network Termination Unit) it can cause trouble...check your ISDN line with telco...
If ISDN line is configured in PTP mode, L2 is always UP, but if it's in PTMP mode telco shuts it down but after first call it goes UP...this configuration corresponds to my telco configuration, maybe it's different in your country with you telco.

Kosagraf,

Elastix-2.0.3 uses dahdi(wcb4xxp) as its driver. No need to do something else except checking your ISDN line is ptp or ptmp. Like mIROS said, you need to check your own cable first. Ask your service provider for more help.

Any question, let me know please!
