The BU lists the end points here
I don’t see the SX20 but considering the C20 is listed it should work but again the BU needs to update this link
Keep in mind the BU is no longer recommending video on MP as the flagship choice, the EMS server can only do voice activated and HMS server uses 3545 MCU which isn’t the flagship product after Tandberg acquisition. So I would move towards Tandberg MCU for enterprise class video conferencing.
With SX20 registered to CUCM, can CUCM use the MCU resource of SX20 for Video conferencing?
Example, i have two 8945 phones, a SX20 and a EX60 all registered on CUCM.
One 8945 places a video call to EX60. Now he wants to add the another 8945 and create a video conf between the 2 8945 and the Ex60, can CUCM use the SX20 MCU for this?
Nope the multi site resource cannot be an adhoc bridge resourc the way you are trying to do. You can look at registering a resource like PVDM3 but with caveats like no CP support or BFCP support or go to a MCU like 4500/5300/8510 for adhoc bridging resource or use conductor and get more flexibility
If you join the participants from the sx20 you are fine since that's the device hosting the bridge. In your scenario you were using other endpoints to start a bridge and for that the resource has to be grabbed by ccm and t multi site bridge isn't defined in ccm it is built into the end point
I have question about if we registered SX20 to CUCM to get MRG, i know SX20 can still using internal MCU 4 party. but have to call from SX20 to other?
and secondly if this group need more than four person in conference group, still can be bridge between internal MCU SX20 and MRG MCU?
Multi site is built into the SX20. This means to engage the built in MCU the end point has to be engaged and has to be involved in the call. You cannot cascade between the Multi site license in the endpoint a MRG resource
Would 3 SX20 (with multisite licences) be able to communicate without the need of a CUCM?
Would it be possible to manually set the ips on these devices for conferences?
I found this thread in the Cisco Support Community that might answer your question.
