shutters on the 5235 IP
Phones do not function.
If you change the IP
address of the RTC on the
3300 ICP (System IP
address on MXe Server),
the 5235 IP Phone
applications will not
function.
To restore these applications:
1. Program a local entry in the
ICP/PBX Networking form that
matches the new IP address of
the RTC (or System IP address
on MXe Server)
or
If you already have an entry in
the ICP/PBX assignment (hot
desk or clustered systems),
change the local entry to match
the new RTC IP address or
System IP address.
2. After you program the local
entry, reboot the 3300 ICP and
the 5235 IP Phones will recover
all the applications.
5702 IP
Phone or
SpectraLink
Wireless
Handset
User experiences audio
interruption on either of
these sets.
User is in a conversation on
either of these phones and a
programmed key becomes
active (for example, ringing
or receiving calls) and the
user experiences a
momentary interruption in
audio reception.
The 5207 IP Phone has 14
programmable keys; the
SpectraLink wireless set
has 13 line select keys. If
you program Direct Station
Select (DSS) or multiline
key appearances with
audible “ring” type into any
of the programmable keys
on these phones, users
may experience audio
interruption during
calls.This interruption
occurs because the
hardware in these phones
does not support two
speech channels.
Do not program DSS or multiline
key appearances with “audible”
ring type on 5207 IP Phones or
SpectraLink wireless sets. If you
need DSS or multiline key
appearances on a phone, you
should program the key
appearances on the 5207 IP
Phone or SpectraLink wireless set
with “no ring” type, or use an IP
Console (Release 5.2 version or
later), a 5215 IP Phone, or a 5220
IP Phone instead of the 5207 IP
Phone or SpectraLink wireless set.
