Thank you Paulo for that and pointing me to the documentation . This is the documentation I needed.

Hi!

That answer is a bit missleading.

Yes, its 4 participants, but thats not 4 calls.

The EX90 (and also other C-Series with multisite) supports

* the local user 

+ 3 external video calls

+ 1 external audio call.

Here from the status of the EX90 on my desk:

*s SystemUnit Software MaxVideoCalls: 3
*s SystemUnit Software MaxAudioCalls: 4
*s SystemUnit State MaxNumberOfCalls: 4
*s SystemUnit State MaxNumberOfActiveCalls: 4

Any yes, on the EX90 it is up to 720p for external participants, but (I would say) the local view

of the combined images is 1080p

And as Paulo also mentioned besides that it is a hardware limit you also need the multisite key

be present on the endpoint.

Hi Martin,

I agree with you, mainly after looking the output from a EX90 that you just posted. But I gave the answer based upon the datasheet for EX series. If you read the document, you are going to find the following statements:

4-way 720p30 Continuous Presence (CP) MultiSite

EX90 only: Four-way embedded SIP/H.323 Multipoint

Well, I don't know what conclusion you can take from that, but for me, it means that EX90 is able to make four HD video calls, without considering itself. Because the word "way" really leads you to think that we are talking about "calls" or "flows". I am sure that I am not the only one to come to this conclusion after reading that document.  =)

However, the xstatus output that you posted is incontestable, so I totally agree with you, although I think that the current datasheet is not clear and specific enough on that matter.

Thanks for clarifying, really helpful as always.

Was my response helpful? Please rate useful replies and remember to mark any solved questions as "answered".

let me rephrase it:

The answer, but even more the documentation can be "a bit" misleading.
