MCU 4501 Presentation Quality and Response

Hi there,

We are currently experiencing difficulties with presentation on a conference using the MCU 4501. The presentation quality is not bad but also not great and when there is movement on the PC like a slide show or plainly moving of the mouse then there is a major lag on the far end side. Sometimes allot of the pixels dont even appear when the screen changes or if a slide changes on the PC giving the Presentation on the conference. We have tested this from multiple units using either edge 95 or mxp3000.

We are streaming the calls at 768kbps on each VC and the MCU quality is set to SD.

If we use an old ISDN MCU then the presentation goes through smoothly with no delay or bad quality images.

Please can someone assist with the matter.

Thanks,

Le Roux Joubert

MCU 4501 Presentation Quality and Response

Hi LeRoux

Can you please let me know a few more details ( what sw versions are the endpoints using, what sw version is the MCU using)

How about point to point calls ( where no MCU calls are involved ) are those wroking fine? - do oyu start experiencing issues only when an MCU it's in call scenario ?

Regards

Cristian

Hi Christian,

Thank for the reply.

Yes I have tested the Presentation from one end point to another. Then it works 100% fine on the network and over ISDN.

This is just an MCU issue.

Thanks.
