Troubleshooting Video Call
 
Last updated: January 16, 2009
 
 
UE-to-UE Video Call
 
This section is only applicable to the lab application and to a test application with the required feature license.
 
- 
Ensure that 
Video Call Type
 is set to
 UE-to-UE
. 
- 
 
The 8960 receiving the UE-to-UE video call origination must be in 
Active Cell Operating Mode
, in
 Idle 
state. 
- 
 
If one of the 8960s is partially preset while up on a UE-to-UE video call, the call to its UE is dropped with no over-the-air signaling. If the other UE does not recognize that the call has dropped (and thus ends the call), you should manually end the call or partially preset its 8960 as well.
 
- 
 
If one of the 8960s is fully preset while up on a UE-to-UE video call, the external device connection is disconnected, which causes both 8960s to end the call with their respective UEs.
 
- 
 
Originating a UE-to-UE video call on your UE may require different key presses than originating a voice call.
 
- 
 
The underlying architecture of the
 External Device Connection 
feature (used to establish a 
UE-to-UE Video Call
) has changed over time. The implementations are not compatible (see 
Troubleshooting External Device Connection
). To establish an
 External Device Connection 
between two test sets, the test sets must have compatible firmware (see www.keysight.com/find/8960upgrades for more information). 
 
 
 
UE-to-8960LAN Video Call
 
This section is only applicable to the lab application.
 
- 
Ensure that 
Video Call Type
 is set to
 UE-to-8960LAN
. 
- 
 
To originate a
 UE-to-8960LAN 
video call from your external device,
 Allow Remote Call Origination State 
must be set to
 On
. 
- 
 
To release the
 UE-to-8960LAN 
video call from your external device,
 Allow Remote Call Release State 
must be set to
 On
. 
- 
 
The timing between the "Video Call Established Indication" from the test set and the arrival of the first data message on the data interface is not specified; either message can arrive at the external device first.
 
- 
 
The timing between the "Video Call Terminated Indication" from the test set and the arrival of the last data message on the data interface is not specified; either message can arrive at the external device last.
 
- 
 
Ensure that your external device is set to send control messages to the UDP port and IP address specified by the 
Control Message Receiving UDP Port
 and 
LAN IP Address
 settings.
 
- 
 
Ensure that your external device is set to receive control messages at the UDP port and IP address specified by the 
Control Message Destination UDP Port
 and 
Control Message Destination IP Address
 settings.
 
- 
 
Ensure that your external device is set to send data messages to the UDP port and IP address specified by the 
Data Message Receiving UDP Port
 and 
LAN IP Address
 settings.
 
- 
 
Ensure that your external device is set to receive data messages at the UDP port and IP address specified by the 
Data Message Destination UDP Port
 and 
Data Message Destination IP Address
 settings.
 
 
 
Loopback Video Call
 
This section is only applicable to the lab application.
 
- 
Ensure that 
Video Call Type
 is set to
 Loopback
. 
- 
 
The 8960 receiving the Loopback video call origination must be in 
Active Cell Operating Mode
, in
 Idle 
state. 
- 
 
Originating a loopback video call on your UE may require different key presses than originating a voice call.
