[asterisk-users] TDM2400 card FXS problems

[wassim darwich]

HI:
I had this problem before with TDM2400P but with fxo modules and VPMADT032 (echo canceller),there was no audio at all.but then i unpulgged the ehco canceller module (VPMADT032) from the TDM2400P board and started the server  and then  i didnt face this issue any more.
In your case  first check the output  of  #dmesg 
if it shows repeated message of "Unable to set SW Companding on channel " ,then your problem is with the echocanceler module (VPMADT032) and do same what i did,dont talk to digium cause they themselves dont know about this error and dont have solution for it ,i tried before without any success.
 
best regards;

I don't know what it showed at that time, I didn't know to look for that.  I'll try to get the customer's permission to re-create the symptoms this weekend and post back with the lsdahdi output.

Thank you,

What's the output of lsdahdi in that case?
