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

[Colin Anderson]

Followup on this issue, it appears that using a single PRI's clock as the
master clock avoids clock drift between the PRI's and we get no more
artifacts. So, : 

wanpipe1.conf:

TE_CLOCK        = NORMAL
TE_REF_CLOCK    = 0

wanpipe2.conf:

TE_CLOCK        = MASTER
TE_REF_CLOCK    = 1

zaptel.conf:

span=1,1,0,esf,b8zs
span=2,0,0,esf,b8zs

< 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.
