[asterisk-users] Sangoma A102 w/ EC module gets intermittent echo/audio artifacts

[Michael L. Young]

< Zaptel.conf:

< loadzone = us
< span=1,1,0,esf,b8zs
< span=2,1,0,esf,b8zs
< bchan=1-23
< dchan=24
< bchan=25-47
< dchan=48

Just a quick thought in looking at the settings above, it appears that you
have set both spans as the primary timing source.  I am pretty sure that
only one span should be the primary timing source.  The other span should
either be at 0 (not used as a timing source) or set as a secondary timing
source.

Hope this helps.
