[Asterisk-Users] Echo Problem with T411P

[James Texter]

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
