Change subject: app_dial: remove pending CONNECTED LINE updates before initialize calls
......................................................................


Patch Set 1:

> > This is a sledgehammer approach that just seems wrong.
 > 
 > app_dial.c
 > The function dial_exec_full while loop through the list of dial
 > destinations and set CONNECTED LINE ID on outgoing channel
 > if OPT_FORCECLID ast_channel_set_connected_line with forced_clid
 > else ast_connected_line_copy_from_caller
 > 
 > The function wait_for_answer calls ast_read on originating channel
 > and to process AST_CONTROL_CONNECTED_LINE calls
 > ast_indicate_data(in, AST_CONTROL_CONNECTED_LINE, f->data.ptr,
 > f->datalen);
 > on outgoing channel.
 > If this is pending AST_CONTROL_CONNECTED_LINE updates it could
 > happen before PJSIP forms INVITE message.
 > So CONNECTED LINE ID replaced by this frame data on outgoing
 > channel.
 > 
 > The pending AST_CONTROL_CONNECTED_LINE update appears at early
 > stage on Local channel ';2' for attandend transfer.
 > core_unreal.c
 > The function unreal_colp_redirect_indicate on AST_CONTROL_CONNECTED_LINE
 > calls ast_connected_line_copy_to_caller where dst='Local/****;2'
 > and src 'Local/****;1'
 > and then build and queue frame AST_CONTROL_CONNECTED_LINE to
 > 'Local/****;2'

I've asked to see the logs demonstrating this on ASTERISK-27980
