<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 c2801-ipvoice-mz.124-4.T5.bin
