Does anyone know if this is hardware limitation or how to increase this parameter? The ad-hoc conferencing parameter is configured for 8 in service parameters. The device pool points to the default software conference bridge.
Looks like its hard coded to 4 for EX90.I tried increasing the value to '5' in my lab on CUCM 9.1.2 and CUCM 10.X built on different platforms but it doesn't allow the number to be increased and results in the following error
"Update failed. DeviceNumPlanMap MaxNumCalls value exceeds the limitation for this type of device"
Thanks Manish for posting that error, it is the same one I get as well.
I was reading through the EX90 document on ad-hoc conferencing. If the design includes the MCU and the configuration below, would this give us what we need? Is this limitation only seen when the device uses its own internal bridge?
Unfortunately, I do not have the MCU for this. There is couple cli commands to verify whether EX90 is using CM or MCU after its configured. I would be interested to know if this would change the device limitation.
To enable ad hoc conferencing the Cisco Unified CM must be set up with a Conference Bridge (media resources), and the conference bridge must be added as a Cisco Telepresence MCU in Cisco Unified CM. Configuration of Cisco Unified CM is described earlier in this guide. Refer to the Multipoint Mode setting in the "Product specific configuration layout" on page 14.
Verifying the setup
The ad hoc conference setup can be verified by running the following command on the endpoint (codec):
xStatus Conference Multipoint Mode
CUCMMediaResourceGroupList: Multiparty conferences (adhoc conferences) will be hosted by the Cisco Unified CM configured conference bridge.
Any other result indicates that the codec is not configured for ad hoc conferences on Cisco Unified CM.
The codec built in bridge setup can be verified by running the following command on the endpoint:
xStatus Conference UseBuiltInBridge
False: The CUCM ad hoc conferencing mode is used.
True: The internal built in bridge on the endpoint is used. Calls will not escalate to any external media resource
I could not find any further details on this with MCU in picture, every reference that i came across had max calls 4. However, i would suggest posting this query under the Telepresence support forum for their thoughts on this

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
