Polycom PVX Release Note page 21

encounter difficulty with call connection or data sharing and your system
is connected to a NAT/firewall, you may experience better results by
disabling one or both of these options in the Polycom PVX application.
• When you are in an audio-only call, you may lose your local video if you
click the PIP button. Local video will return once the call is terminated. To
avoid losing local video, do not click the PIP button in an audio-only call.
• If your system is registered with a gatekeeper, you must use quotes when
you call an alias or extension that includes a space in the name. For
example, to dial Polycom Austin as an alias, you must enter "Polycom
Austin" in the address field to connect the call.
• When placing a call from the Directory dialog either by manually entering
an address or by selecting a number from a directory, use the Call Quality
list to choose a call rate for that address. The selected rate will override the
rate stored in the directory for that number. If you choose a different
address from the directory, the call will be placed using the rate stored in
the directory rather than the Call Quality override rate.
• If you change the available speeds on the directory list or remove the
current directory default speed, you must go back to the directory and
explicitly change to the new speed. If you do not select a new speed in the
directory, Polycom PVX will continue to place calls at the previous default
speed, even though that speed no longer appears in the list. Go to the
Network > Bandwidth page and click on the Call Speeds button to select
up to six speed settings.
• If you are having problems with E.164 or ISDN dialing, check that the Dial
using H.323 extension when connected to a gatekeeper setting is enabled
on the Setup > Directory page.
• You may see incorrect information in the Recent Calls list when dialing
E.164 prefixes through an MCU.
• Encryption is not supported when the system is registered to a gatekeeper
that is configured to do H.245 routed signaling. Either change the AES
Encryption setting to Off on the Setup > General > Call Settings page or
disable H.245 routed signaling on the gatekeeper.
• The use of the Call Forwarding feature requires that your system be
registered with a gatekeeper. Once you have registered your system with
a gatekeeper, the Call Forwarding options will be enabled.
• The use of People+Content requires calling speeds above 128 kbps.
• When dialing into a password-protected VSX™ multipoint call from PVX,
you may encounter black video for up to 30 seconds. During this time, the
far-site system is being prompted to accept or decline your incoming call.
PVX endpoints will not be prompted to enter a password.
• Once you have closed a PVX chat session, you must reactivate data
sharing by turning it off and then on again before beginning a new chat
session.
• The Maximum Call Rate setting on the Bandwidth tab under Setup >
Network does not currently apply to inbound SIP calls.
• Dynamic bandwidth allocation is not currently supported in SIP calls.
