Hello Liviu:
Yes, the Cisco ** appears ** to be a PSTN on one side & SIP/DATA traffic to
the other... and yes it has DSP modules. But the issue here is there are
NO PSTN's. The PSTN lines that appears to be present are connected to the
Digium FXO - are in fact **NOT** functional.
The folks in the office were made to believe that if their T1 for Data is
down -- the PSTN will kick in for receiving and sending calls. Basically
ALL phone traffic is through VoIP through the T1's data channel (SIP to
Asterisk). For the past 30 or so days, the office has been running
flawlessly. But since their T1 went down the promise of a "redundancy"
never took place and the techs who installed the system were no where to be
found.
Ultimately from what I gather and from the setup that I have seen at other
offices that truly have their T1 for voice(PSTN -- note I'm not saying VoIP)
& data(for internet) , this particular office's setup is **STRICTLY** data
on the T1. In today's small to medium sized offices I'm not convinced
one can justify the cost of a T1 - where you can get DSL, cable for a
fraction of the price for the office's internet needs.
Now if the office were to use at any given time 10+ simultaneous incoming
and outgoing calls with the plans to expand in the future to more
agents/employees, then yes... I can see T1 Voice/PSTN being a justifiable
option. That's just my 2 cents.
Cheers!
Reza.

Was that a T1 for voice or for data ? If it was for data, I would
understand - I haven't seen a Linksys/Dlink/other router that could
take a data T1 connection. However,
a second hand Cisco 1600 series could handle that and could be
purchased on eBay for $100-200.
If it was a voice T1 and the Cisco router was supposed to be the
gateway between PSTN on one side and SIP to Asterisk on the other
side, then the router would have to be quite expensive, because of the
DSP modules (PVDMs)

HI Reza,
Do you mean that Cisco 1700 runs an Asterisk with a P3 chip inside as a
submodule?
tks

machines running on a P3 machine (never mind the configurations) -- which
has 2, 4 port Digium Cards -- sold for $25,000+ fairly recently. Heck
if I
sold a P3 for that much, I'd make sure the client got customer service
