specified by local IP address
Disable SIP – see

for 60 seconds but then TANDBERG FieldView Application reports Call Failed.
Cause

Firewall is modifying SIP packets.
Some firewalls modify SIP packets to assist with NAT/PAT
traversal. This is not desired for FieldView operation. For Cisco
firewalls the command to disable this feature is (depends on
model/version):
no fixup protocol sip 5060
, or
no ip nat service sip udp port 5060
;
no ip nat
service sip tcp port 5060
Call attempt from TANDBERG FieldView Device fails after 60 sec with Session disconnected and no ringing
at TANDBERG FieldView Application
Cause
Solution
The PC has multiple network adapters/
connections.
If this includes a VPN connection, quit TANDBERG FieldView
Application and then disable the VPN network.
Session disconnects when video streaming enabled.
Cause
Solution
Insufficient bandwidth available.
Select a lower bandwidth configuration. See
Call Window
.
To quickly evaluate the bandwidth at the PC end, use a speed
test tool such as
www.dslreports.com/speedtest
.
Session disconnects when TANDBERG FieldView Device roams to a new access point.
Cause
Solution
New access point is on a different IP subnet so
the TANDBERG FieldView Devices IP address is no
longer valid.
Initiate a new call. It may be necessary to power cycle the
TANDBERG FieldView Device so it acquires a new IP address.
