Reliability and Performance

All 1600 Series IP Deskphones respond to a ping or traceroute message sent from the DEFINITY
MultiVantage™, Avaya Aura Communication Manager, or Avaya Aura Communication Manager
Branch system (formerly known as Avaya Distributed Office) or any other network source. The
deskphones do not originate a ping or traceroute. The 1600 Series IP Deskphones offer and support
"remote ping" and "remote traceroute." The switch can instruct the deskphone to originate a ping or a
traceroute to a specified IP address. The deskphone carries out that instruction and sends a message
to the switch indicating the results. For more information, see your switch administration
documentation.
If applicable, the deskphones test whether the network Ethernet switch port supports IEEE 802.1P/Q
tagged frames by ARPing the router with a tagged frame. For more information, see
Considerations on page 72. If your LAN environment includes Virtual LANs (VLANs), your router must
respond to ARPs for VLAN tagging to work properly.

QoS

For more information about the extent to which your network can support any or all of the QoS
initiatives, see your LAN equipment documentation. See
the 1600 Series IP Deskphones.
All 1600 Series IP Deskphones provide some detail about network audio quality. For more information
see, Network Audio Quality Display on 1600 Series IP Deskphones
