Santiago:
Ok then you can use asterisk as the "gateway" between the PSTN and an
internal VoIP network. I assume you do not want to purchase any analog
phones or VoIP phones, just PCs with a good sound card, speakers and a
microphone? You did not clarify if your internal users were running Linux or
Windows.
For Linux GnoPhone is an excellent PC based phone client and it speaks IAX,
a very light weight VoIP protocol just for Asterisk. By the way if you want
go with VoIP phones, the Snom phone is the only hardware VoIP phone I know
of that speaks IAX and lots of people are out there using it now.
For Windows I have used MSN messenger 4.7, SIP and GSM codec and get so so
performance from that combination. There are lots of other ones out there
that will speak to Asterisk using H323 and SIP. I just do not know what they
are cause I have no big need for them.
You still have to connect yourself to the PSTN through your phone provider
of choice in your location. In Columbia I am not sure who that would be and
what type of service you can get. T1 vs E1 for example. Perhaps someone on
the list can help you out in that respect. Any Columbian Asterisk users out
there?

thanks for the answer,
we need to use the data network for the transport of the voice, with the
pcs as telephone devices, with h323 (possibly), and can interact with
the PSTN (there is not VoIP providers here)
thanks again,
