Wow, this is a completely neutral and very valuable review. Thanks a lot
Zoa.
I´m an * newbie; my little box will only needs 20 extensions to give
termination to remote users and I´m about to buy a PRI interface; I
decide to get Sangoma hardware.. a lot of people recommended it to me.
In you review you said: "The biggest choice you need to make is if you
want onboard echo cancellation or not". How can I really know if I will
need echo cancellation? I´m planning to get a single span card (which
doesn´t include echo cancellation) but how can I know if I really need
this feature??
Thanks in advance.
