Title: Re: [Asterisk-Users] Echo Problem with T411P
Try setting echocancelwhenbridged=yes.  Also, in your zaptel, you only need to define one span as the clock master, so should be like

zaptel.conf------------------------------
span = 1,1,0,ccs,hdb3,crc4
bchan = 1-15,17-31
dchan = 16
 
span = 2,0,0,ccs,hdb3
bchan = 32-46,48-62
dchan = 47
 
span = 3,0,0,ccs,hdb3,crc4
bchan = 63-77,79-93
dchan = 78
 
span = 4,0,0,ccs,hdb3
bchan = 94-108,110-124
dchan = 109
 
loadzone = nl
defaultzone = nl

Thanks,

James

Hello,
 
There are 3 PRI’s connected to the card each from different operators. Especially echo occured on span 3 is really annoying. Configuration files are as follows. Is there something wrong in conf ?
