Hi Chris,
Thank you. lua presence.lua is now working without error output.
Calling via dial plan seems to have another problem.
EXECUTE sofia/internal/91 at 192.168.130.12 lua(set_presence.lua vm_blf_extension confirmed)
2015-03-31 10:47:20.995581 [ERR] mod_lua.cpp:203 /usr/local/freeswitch/scripts/presence.lua:6: attempt to index local 'self' (a nil value)
stack traceback:
/usr/local/freeswitch/scripts/presence.lua:6: in function 'new'
/usr/local/freeswitch/scripts/set_presence.lua:7: in main chunk
The line 6 contains the following:
self.__index = self
Have you another idea?
The program versions are:
FreeSWITCH Version 1.4.15+git~20141229T185951Z~507a0f22c5~64bit (git 507a0f2 2014-12-29 18:59:51Z 64bit)
