i had similar problem when using sangoma pcix when i used the old wanpipe*.conf stuff without some changes made in their changelog for the new wanpipe drivers. i had one way audio or complete loss of audio.<br><br>however, since i made the changes to the e1 card configs, everything seems to have been okay now.
