[Asterisk-Users] Echo Cancel with sangoma o digium

[Erick Perez]

I have to purchase an E1 card to connect an asterisk to the phone
company. Should I go with echocan in hardware (sangoma does not seem
to have is in its a102/101 models) of should I use software
cancellers?

My phones will be SIP-only and a few fax machines connected to
grandstream FSX-to-SIP units.

Thanks,
