I have a CUCM 9.1 with 8900 phones, Ex60 and 2911GW (PVDM3-256).
I am trying to configure a video conference that would allow three+ EX60 in a conference !!!
I configured two conferences :homogenous and heterogeoneous. Both worked fine as long as only one Ex60 was in the conference (the rest of the participants were 8941). When two Ex60 participants are in a conference the screen of one of them freezes.
Is it possible to have the type of conference I want (I think is not supported by cisco for now)?
