Missing file mISDN_dsp_oslec

Hello,

I useing IPFire 2.15 Core 78 with the PAE Kernel and the addon Asterisk with LCR. During the reboot I get the information mISDN = Failed and the message mISDN_dsp_oslec not found.

Asterisk works (not stabel) with an USB-ISDN device. 1)I get a warning from the Kernel. I think it caused from the USB driver. 2) Sometimes a connection can't establish at the first time. If you try again the connection works.

Regards

Michael
