Hello,

i have a proble with calls via ISDN. I can't hear the caller. But the caller hear me. Everything work fine with internal calls and calls via sipgate.

Software: Asterisk 1.8.19.0, LCR Version 1.12 and Misdn

Misdn Info:
Port 0 'hfc-pci.1': TE/NT-mode BRI S/T (for phone lines & phones)
2 B-channels: 1-2
B-protocols: RAW HDLC X75slp L2:DSP L2:DSPHDLC

I've looks in some log-files. This was the only thing it looks like a problem:

LCR-LOG:
