Hi Schneiderham,
The maximum number of outgoing messages including indirect messages is defined with NWK_MAX_DATABUFS_TOTAL in nwk_globals.c. Also, the maximum number of indirect messages per device is defined with NWK_INDIRECT_MSG_MAX_PER in the same file. So I would say you can increase the maximum number of indirect messages by increasing both NWK_MAX_DATABUFS_TOTAL and NWK_MAX_INDIRECT_MSG_MAX_PER. By the way, please note that NWK_MAX_INDIRECT_MSG_MAX_PER should not be greater than half NWK_MAX_DATABUFS_TOTAL.
