Well I figured out why pbx_builtin_setvar_helper() isn't cutting it, but I'm 
still no farther ahead.

ast_request_and_dial doesn't return until AFTER the channel's been created and 
dialled, so pbx_builtin_setvar_helper() is too late.

No problem, I create an outgoing_helper structure and write the variable in 
the vars structure pointer and use __ast_request_and_dial instead of 
ast_request_and_dial:

        snprintf(buf, sizeof(buf), "%i", lot);
        memset(&oh, 0, sizeof(struct outgoing_helper));
        oh.vars = ast_variable_new("PARKEDAT", buf);

        dchan = __ast_request_and_dial(dialtech, AST_FORMAT_SLINEAR, 
dialstr,30000, &outstate, chan->cid.cid_num, chan->cid.cid_name, &oh);

So now I'm creating the variable before the channel is connected to Dial, so I 
should be able to see the PARKEDAT variable...  Unfortunately this isn't 
true.

This is truly baffling.  Can anyone help?
