Refer to section 1.76 support for additive licenses in HMP 4.1 Linux release update notes:
www.dialogic.com/.../release_update.pdf
You can use a conf command as noted to enable all licenses in a certain license folder.
For the other "out of resource error" it appears you may not be setting you IP_CAPABILTY structure correctly for that channel in correlation to what is available in the HMP license.
