The “tone_detect” api is not working correctly, in mod_commands.c on line 267 the declaration of argv should be changed from “char *argv[6]” à “char *argv[7]” since there are 7 parameters involved.

Also in switch_ivr_async.c on line 626 I believe that the log level should be changed from ERROR into DEBUG or probably NOTICE

Last, in order to compile it on MS Visual Studio 2005 I needed to do 2 casts on switch_ivr_play_say.c  on both lines 945 and 948 you have to cast “olen” as a “uint32_t” in order to avoid the warning and thus the error.
