We have asterisk server which have hfcs isdn adapter acting as FXO and mediatrix units as FXS on another site connected with 2mbit link. The trouble is that when I connect from asterisk server to mediatrix unit; whatever comes to asterisk is heard OK (no noise, minimum jitter; absolutely acceptable voice quality), but whatever is sent to mediatrix unit is heard with noise, garbgled or completely cut-off. I have tried with ulaw/alaw and g729 (I could not find support for g723) and it is simply the same. I have reconfigured mediatrix unit hundreds of times with no success; does anybody have any ideas what to do or to try? ---- The linuX Files -- The Source is Out There. mailto:marko@printel.hr http://printel.hr
