PhoneApps Commercial Module vs DPMM

The commercial End Point Manager module, available separately, is required to use the FreePBX Phone Apps. The Phone Apps module needs to receive data from End Point Manager in order for most applications to work correctly.

@lgaetz I remember Endpoint Manager is free for Sangoma D&P series phone , the question is with that being said, do i still need to go with PhoneApps commercial module in order to take advantage of all its features ?
Any sight on this would much appreciated .

Thanks !
