Thanks again Rich. I hope you dont mind to answer a few more
questions....
My response is inline...
Hi! and thanks a million for your answer. You hace cleared many of the
doubts I had, including the differences between the cards. At the same
time, new questions has arised:
Is there a possible configuration in case I dont have a broadband
connection in the called-end, for example, a modem connection?
No, there is no modem support built into asterisk. The problem is that
modems typcially do not support the bandwidth needed for a single
phone call. About the minimum bandwidth needed (including IP overhead)
is roughly 30,000 bits/second full duplex.
Could I cheat Asterisk by connecting the linux boxing it's running to a
LAN which is connected to the internet using a Modem? In this way,
Asterisk will see a broadband connection... this is assuming I dont
care about the problem with the bandwith of course.
Is it possible to set a route for the IP packages? This is to optimize
the packets transmission over internet.
I'm not sure what you mean with the above question. The voip packets
will typically be standard old UDP packets, and those packets are routed
over the Internet like any other IP packet based on whatever the ISP's
have elected to do. You don't have any choice on how those are routed
in any case.
That's exactly what I asked....
I'm outside US, so, why should I use tdm instead of x100p?
The chip set on the x100p was designed specifically to match the US
telco standards. The card will work in some countries, but other
countries you'll hear a lot of echo, callerid may not work, etc, etc.
The TDM card has a much newer chip set that was intended to be used
in many different countries around the world. Therefore, stay with
the TDM (as opposed to the x100p).
Rich
OK. And thanks again.
