EPM - Grandstream DP715 with multiple handsets

Hi everyone. I am fairly new to the commercial EPM. I have a Grandstream DP715 with additional handsets. I cannot see any means of being able to provision the additional handsets. Is it possible within the EPM, or do all the additional handsets need to be manually configured through the GUI on the DP715 base?

If it has to be manually configured, is there any other multi handset DECT system that is fully configurable through the EPM?

Thanks in advance of any info you have!

Yes you should be able to do this. In Extension Mapping add another extension to the same MAC and pick Account 2 to make it be Handset 2.

how do we do this on the DP750/DP720 …since the DP715 is EOL?
