Strange Problem With TDM2400P


I am having a strange problem with TDM2400P, my card is populated with all FXO modules, problem that I am facing is that when I call on Channel 1-12 Asterisk doesnt recognize any activity on the channel but when I call on any channel from 13-24 everything works fine.

Anybody else ever had the same problem ?


faulty card/modules ? incorrect config ? cables not connected ?

yeah it had a faulty module

I removed the faulty module and everything is working fine now

but I dont understand why 12 channels weren’t working becuase of 1 faulty modules :confused:
