[Asterisk-Users] Static on inside end of conversation

[Jeff Busch]

This definitely could be the issue.  I am running 15 total devices (7
IP500 phones and 7 PC's along with a networked fax/scanner, and the
Asterisk Server) through a single 16 port switch.  

We run one MS Access app on almost all the desktops that is a
client/server app that creates a lot of traffic.  I will go to the site
tomorrow and make some changes to the topology of the LAN.

Thanks!

Jeff

We've seen echo on congested LANs within our Enterprise. I'm not sure if
this fits what your seeing or not. We've placed phones in their own vlan
and added 802.1p QoS to expedite forwarding upto the first hop router
for the outbound call leg and the echo is gone. We did the same for the
inbound call leg also.
