[Asterisk-Users] FAX x Echo Cancellation

[Isamar Maia]

I installed a TDM04b and a TDM40b with aggressive echo suppression
and it's working almost perfectly.
The problem is that all extensions are fax machines and people uses it for
both purposes, voice and fax. AFAIK, I cannot use aggressive suppression
for fax extensions, but when I turn it off terrible echos happen.
Is there any workaround for this case?

Thanks,
Isamar
