[Asterisk-Users] No sound on 10% of incoming calls

Tue Feb 7 11:07:58 MST 2006

What do you do with the other 15 channels?

your zapata.conf says:
channel => 1-15 ;,17-31 => only 15 first channels on PRI

but your zaptel.conf says:
span=1,1,0,ccs,hdb3
bchan = 1-15, 17-31

You use all 30 channels in Zaptel.conf but only 15 in zapta.conf
I never configured Zap on asterisk and frankly do not have a clue how to 
and I do not have a clue what  the both files do, but the use of 15 
channels only, makes me wonder.

Did you make a ISDN trace what do the Setup message etc... say which 
channel is requested by France Telecom and on which channel is the call 
setup?

Why I ask.
Dead air (2way) usually means channel mismatch, seen this happen many 
times, the D channel is on kick 16 and you have 15 channels in one file 
configured and 30 in another.

Why only 15 channels?
