by Hi.
I am looking for the IP-telephony getaway which can be run on linux
box with USR voice-modem. So far i haven't find any ready solution.
I can imagine, that it should be possible: GSM compression library is
avaluble, USR uses GSM as internal voice format (Vgetty is an
example). A bunch of IP-phone software also exist, i think some of
them use GSM as voice format. So running something like voice daemon
on this box and using some IP-phone software on the other side?
This is the hardware setup:
I have a linux box on a relatively good network connection with a USR
voice-modem which i use as ppp dial-up server/fax getaway in my home
town. And i would like to call back home (for free) when i am away
using internet. Generally, i have access to university net, which is
relatively fast, so all the low-bandwidth problems can be omitted so
far (not exactly, but this connection is better that modems, i can get
8-10 kb/sec, up to 15-20 nights/weekends ftp from US to Russia).
I would greatly appreciate any pointers in this direction.
