<DIV>Hi,<BR><BR>Got remote site with 2801 and 6 users. When these users phone HQ
over the WAN they sometimes loose the audio (remote site can't hear HQ but HQ
can still hear remote site) and this happens intermittent. Funny thing is that
if remote site puts HQ user on hold when there is no audio nad take them off
hold - normal audio works both ways again. All other Remote sites does not have
this problem. Remote site 2801 has following config running
