[Freeswitch-users] FXO/FXS card advice

[ocset]

Hi

As a new member of the forum, I am curious to know your experience with 
FXO/FXS cards.

I have a SPA3102 and have configured it to work with FS, but it feels a 
bit like I am trying to make a square peg fit a round hole. I am hoping 
to implement FS at a business which currently has 4 POTS lines and would 
prefer to use an internal IDE card for the job of integrating these 
phone lines into FreeSwitch.

Has anyone got some advice on which cards I should be looking at that 
just "work" with FS? What about echo cancellation - is that something I 
should just cater for or does it depend on the client situation? What 
about software cancellation?

This seems like one of those times when too much choice is a bad thing 
and I need some guidance on what has worked for you.

All advice would be greatly appreciated.

Regards
