Bad display on MX700 with 3 endpoints connected

Bad display on MX700 with 3 endpoints connected | TelePresence | Cisco Support Community

Hello,

we have 3 MX700 (dual screens) with multisite licence and tried a conference between the 3 sites but we had a bad comportment on the third site connected...

Let's assume the following :

- Site1 calls site2 : site1 and site2 see each other on separate screens as expected

- Site1 calls site3 in order to join them to the conference and then here is the result :

* site1 sees site2 and site3 on separated screens as expected

* site2 sees site1 and site3 on separated screens as expected

* site3 sees site1 ans site2 on the same screen and the other screen is only usable for a shared presentation or to see the local camera

It was impossible for site3 to change the layout of the display. The only possible thing was to move the image of the local camera on the differents screens but it was impossible to see site1 and site2 on different screens. It's really annoying because it displays site1 and site2 in small on the same screen.

For information, on the Touch 10, the screen who was displaying site1 and site2 was named only with "site1" name. There was no mention at all of site2 anywhere as if the video stream was coming only from site1 who was calling.

Can somebody help us with this ?

Thank you in advance for your help and best regards.

Have you compaired the configuration of the working endpoints with the not working one?

What happens if you take a configuration backup of a working endpoint, and restore it to the not working one? Be sure to change IP, H323, and SIP information within the backup file prior to the restore.

Hello,

yes we compared the configuration but it seens the same and I am pretty sure that if we connect with site3 before site2 the problem will appear with site2 but I am unable to test it right now because site2 is in another timezone and I have not a lot of contacts there...

If I'm understanding the call scenarios correctly - your assumptions are incorrect. Only the MX that's hosting the call will see the other far ends on separate screens. The standard functionality of SIP/H.323 allows for one live video stream plus a second one for content. Cisco Telepresence Server has a feature called "multistream" which can send more than one live stream, but the multisite built into the codec does not. The site hosting the call - in your example site one - they can see sites 2 and 3 on separate screens because they are in calls with each of them. 

In your bullets - if site 1 called 2 and 3, only site 1 would see both separately. You suggest site two does, but it would not unless site two called 1 and 3. 

If site 1 called 2 and 3, site 1 would show 2 and 3 on the two screens if there was no content, and they combine them on 1 screen if there is content. Sites 2 and 3 would only show the combined (continuous presence usually) image on the primary and the second would stay off unless there was content.

Hello Patrick,

thank you for your answer. If we put a new scenario, can we have what we want ?

- site 1 calls site 2

- site 2 calls site 3

Could it be ok with this ?

And about the "multistream" option. Do we have to only buy a new licence or is it a new server ? For information we already have a CUCM server...

Thank you for your help.

If 1 calls 2 and 2 calls 3, then you are hosting on 2, so they will see 1 and 3 on separate screens. 1 and 3 will not show the other two on separate screens. There is no way you can have a three way call with each system showing the other two separately with the equipment you have - multisite does not work that way. 

Multistream is a feature with the Cisco Telepresence Server. To deploy it you'd need to install Conductor and at least one virtual TPS. This would give you what you want.

In addition to Patrick M's comments, here is a good example of how to enable Multistream including the requirements needed to make the solution work.

Great !

Thank you !

Hello Patrick,

I just have one more question. I browsed a little the Cisco Website and it also exists the "Cisco Meeting Server" (ex. Acano) besides the "Cisco Telepresence Server".

Would it also be possible to do it with Cisco Meeting Server or not ? And can you tell me what are the differences between CMS and CTS ?

Thank you in advance for your help.

CMS is the preferred platform going forward, but because you are specifically looking for multi stream functionality I mentioned TPS. It's my understanding that multi stream is coming for CMS, but it's not there today.  CMS is otherwise a better solution - it scales better, doesn't use/require Conductor, but I can't make any promises on when multi stream will be added. You might want to check with your Cisco rep on that.
