I’m getting a lot of this messages on asterisk console:
chan_zap.c:8194 pri_dchannel: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2
I’m just starting with asterisk. Could someone explain, please, what are those HDLC, FCS and (8).
As far as I understood from google this message basicly means that a wrong packet on an E1 line has been received. Is that bad? If so, where I should be looking for a problem (software, digium card, actual E1 line).
Thanks in advance
