Hi, 


  I'm having the same problems in echo cancellations that are mentioning
in this mail of the list
http://lists.digium.com/pipermail/asterisk-users/2003-July/016073.html ,
but I haven't found some reply to this mail. 

I haven't echo problem on outcoming calls but echo cancellation is
disabled in zaptel channels in incoming calls. Status of zaptel channel
is the next:

localhost*CLI> zap show channel 32
Channel: 32LI>
File Descriptor: 49

PRI Flags: Call

I don't know because Asterisk doesn't enable echo cancelation.
