Avaya 4600 Series IP Telephones
Issue 3.4.1 June 2005

To enhance the reliability of IP telephones, phones now have the option of retaining their DHCP
lease in the event of a DHCP server failure. Users still have the option of strictly interpreting the
DHCP standard, in which case the IP telephone will give up its IP address after its lease expires
if the DHCP server is unavailable. In the new operational mode, the IP telephones may retain
their IP address after lease expiration while sending DHCP requests once per minute and ARP
requests for their IP address every five seconds. If another entity responds to the ARP request,
the phone immediately releases its address and reinitializes DHCP discovery.
An application enablement enhancement for release 2.2 is "Push". Push allows audio streams,
text strings, and web pages to be "pushed" from a PC application directly to the phone. There
are two priorities: normal and barge-in. Barge-in pushes go through to the user unless the
phone is in Local Procedure mode or restoring a back-up file, while normal is more restrictive
(e.g. audio push would fail if the user were on a call). If a user is not on a call, audio pushes
would take the speaker off-hook. If a user is on a call, barge-in audio pushes would put the far
end on hold. Normal pushes are expected to be used for non-essential information (e.g.
"Birthday cake in Joe’s office"), while barge-ins would be used for critical information worthy of
interruption (e.g. audio plays, "The building is closing due to snow," while the browser displays a
weather report).
Avaya 4601 IP Telephone
The Avaya 4601 IP Telephone is a low-end phone designed for reception areas and other
applications where cost is the driving factor. It is similar to the 4602, however, it lacks a display.
