Plantronics + Polycom.
Now together as
We frequently must connect on a Cisco TelePresence MCU MSE 8510 ( Software version 4.4(3.49) - Build 6.18(3.49)).
This MCU has 3 IP addresses.
For one of these address it's OK.
For the 2 others i can't see video, only sound is OK.
For these 2 addreses the call report shows that video format and protocols are differents in Tx and Rx :
video protocol Tx : H264 / video protocol Rx: H263
video format Tx:798x488 / video format Rx: 4CIF
We make calls in H323
The system software is 4.1.3-111080
Any idea ?
