[Freeswitch-users] Echo cancellation needed?

[Niall Crosby]

Dear FS users,

If I am getting Sangoma hardware to connect Freeswitch to E1, should I
get a card with echo cancellation or not?

Also, is there any advantage to PCIe over PCI? (I understand the
difference between these and am gonig with PCIe, just checking encase
there are legacy issues that make PCIe wrong choice)

Many thanks,
Niall.
