Hi Guys, if anybody knows a good source of AGI scripting tutorials in C language, plz share. I have read the pdf book ‘Asterisk TFOT’, but the author uses languages other than C.

Also if anybody knows a complete list of AGI builtin function (library) plz share.

Thanx in advance

i need to redirect the channel using AGI script. i dont see any command which will do that. So is it even possible to do that in AGI script?
