The EX90 endpoint has native 4-person multi-party call support, while the EX60 supports only person-to-person. But if one purchases the MeetMe bridge subscription, can, say, six EX60s be deployed to handle a 6-party video call?
As per disussion : https://supportforums.cisco.com/docs/DOC-22679
it seems that you get video access URI, which i think you can configure in EX60 in Multiwy settings.
After this configuration your setup will work for Multiway call.
In addition to what Vivek mentioned you can also check the meetme features at below URL.
Gents: Thank you for the information and links. But I seek confirmation that a Meetme (video) subscription works with non-multiway SMB telepresence endpoints.
For example: Can a company with, say, 9 offices in 4 U.S. Domestic locations, purchase 9 EX60 endpoints (none of which natively support Multiway) + purchasw a 12-port MeetMe subscription, and thereby conduct 9-way video conference calls between the 9 office locations?
Or, does the use of the EX60 prevent the use of the 6 or 12 port MeetMe bridge?
