[SR-Users] Dialog order of operations

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,
