I'm looking to install a system with 80 FXS analog phones.
At this time the only cost effective solution is using a 4 port T1 card and
addit 600 channel bank.
Has anyone tried this solution? any good documents beside

as far as i know, addit 600 T1 interface is not PRI (please correct me if
i'm wrong) its CAS robbed bit, will that work with new Digium quad T1 like
TE410P ?( I prefer to use Digium if possible)
The system is connected to the Telco through SIP trunk so all we have in
terms of analog is local loop, Do we need to have echo cancel in this
scenario ?
Thanks!
