UCM 6510 Ring Group Capacity


Can anyone tell me the number of ring groups that can be programmed on a UCM. Looking at the numbering scheme it suggests there are 100 6400-6499.
I am moving a customer base from a 6208 to 6510 and the 6208 had 74 ring groups operating
I have been programming the 6510 and got to 50 and the +Add button Greyed out not allowing me to add any more RG.
looked through documentation on FW upgrades and install guides but no mention of capacities decreasing in fact no mention of capacities at all.


Looks like you found a bug in the 6510 version of the firmware. You need to open a ticket with Grandstream if you are a reseller or get your reseller to do it for you if you are not.
