Subject: chan_lcr has now a lcr_request function which should work basically, we only need... 
X-Git-Url: http://git.eversberg.eu/gitweb.cgi?p=lcr.git;a=commitdiff_plain;h=350450b9cadc6107449fe2630843d4f898f680b7

chan_lcr has now a lcr_request function which should work basically, we only need the callref request mechanism here. We have also a lcr_ast_new function which produces an empty Asterisk channel object. The Call handler has now a pointer to the asterisk channel, the asterisk channel also holds a pointer to the Call handle, so they need to be created and destroyed together at the same time.
