lang=EN-GB>Longshine LCS-8051 with HFC-S-Chip (NT-Mode) together with the chan_misdn.
I build the system like it was explained at <a href="http://isdn.jolly.de/">http://isdn.jolly.de</a>.
At first I used the pbx4linux software from jolly (<a
href="http://isdn.jolly.de/">http://isdn.jolly.de</a>) and then I changed to
asterisk. Both systems works fine, but I have (in both systems) the same echo
problem. When I call a person (ISDN to ISDN), I have an echo, and the other
person has no echo! But when I call to a cell phone (ISDN to GSM), I don’t
have an echo! So this works fine.</span></p>
