Hi all 


I have 6 group 500 series, Out of which 3 codec are used in one location to connect to 3 codecs at other location. Ie: A (3 codecs and B 3 codecs) 

I using this setup as class room telepresence setup with other audiovisual intergated systems. 

Location A: 

codec 1 transmitting Professor Audio, Codec 2 transmitting Left students audio. Codec 3 transmitting Right students audio. 

Similarly we have same kind of setup at B location 

By using integrated system we are dailing all the three codec at once. Where professor and students live secessions happens.

ISSUE Faced: 

During paraller transmission the audio is getting squeezed and unable to understand the both student and professor audio. 

As contacted the network team they have said there is no issue with bandwidth as we have 30mbps of bandwidth. 

We are unable to trace this issue for many days..

Hello @Artha,

welcome to the Polycom Community.

It is always useful to include the currently used Software version as issues experienced or a question asked may already be addressed in a newer release.

Please also include if you are using any additional Polycom infrastructure.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
