[SR-Users] Dialog order of operations

[Alex Balashov]

Hi,

The dialog module documentation remains unclear about the order of 
operations with regard to when to call dlg_manage() or set the 
transaction flag.

My impression is that dlg_manage() only registered TM callbacks, so it 
doesn't matter when you call it, as long as it's before t_relay(). 
However, the documentation neither confirms nor denies this.

So, this raises the questions:

1) Is this okay?

    set_dlg_profile("caller", "$fU");
    dlg_manage();
    ...
    t_relay();

Or do I need to do this?

    dlg_manage();
    set_dlg_profile("caller", "$fU");
    ...
    t_relay();

2) What about setting dialog-persistent variables? Is this okay?

    $dlg_var(account_id) = 49555;
    dlg_manage();

If so, where does the variable go if I never call dlg_manage() because 
the call is aborted beforehand, e.g.

    $dlg_var(account_id) = 49555;

    sl_send_reply("403", "Forbidden");
    exit;

    dlg_manage();

    ...

    t_relay();

3) Any other gotchas or caveats in relation to the order of operations?

I suppose my preference would be to set the dialog profiles in various 
places throughout call processing and call dlg_manage() at the very end, 
right before t_relay(). Is this acceptable?

Thanks,

-- Alex
