+## NOTE:
+## This library uses the PJSUA library which is officially deprecated
+## The reason for this is that I couldn't get this to work with equivalent
+##   code for PJSUA2.
+## At time of publishing, the only library version of pjsua available
+##   in the repos for Debian 9 is the deprecated PJSUA (python-pjsua)
+## Please also be aware that, by default, playlist length is limited
+##   to 64 items. I can find no reason for this limitation, and it is
+##   specific to the python bindings for the PJSUA library.
+## If you'd like to have a playlist longer than 64 items, you will need to
+##   recompile python-pjsua with the appropriate adjustment to _pjsua.c line 2515
+##
+## If you can get this working using PJSUA2, a pull request would be greatly
+##   appreciated.
