MCU warning "H.264 TX capability exceeds advertised RX (MBPS)"

[hashimoto.kotaro]

Hi all,

Sometimes I see errors below in MCU5320(Ver.4.5(1.45)) event log when we make calls from MCU to endpoints.

And when these error appear, call fail.

Does anybody know what these errors mean?

608     14:14:00.683      H.323     Warning     H.264 TX capability exceeds advertised RX (MBPS)
609     14:14:00.683      H.323     Warning     maxMBPS=11880, requiredMaxMBPS=108000, customMaxMacroBlocksPerSecond=40500

not sure, what kind of endpoints did you use, and what kind of bandwidth did they try to use?

Does it help if you use a lower call rate on the endpoint or if you limit the bandwidth 

via your call control?

Thank you Martin,

I'll try and update this discussion.

I experienced the same message in my MCU during a VTC call last week.

Is this a bandwidth issue and can it be addressed from the MCU or endpoint/
