Re: Re: PRACK over PROXY dropped -- ReliableResponse not found

Jens,

My development PC is just up again, after a long period of being 
disconnected. Here's an update on what I can tell

First of all, it is easier to have AUTOMATIC_DIALOG_SUPPORT set to "on" (the 
default setting if you don't set it, like the example does). Alternatively, 
you can use sipProvider.getNewDialog for this

Then, as you can see in the PRACK example, it is possible to not use 
'createReliableResponse' and still get things to work. What is important, is 
to use 'dialog.sendReliableProvisionalResponse'. This will do the internal 
bookkeeping needed to match the PRACK

If you say the dialog is null, then that's the problem. You need the dialog 
object to invoke sendReliableProvisionalResponse on. And since you're saying 
that the PRACK example does work, I suppose the dialog is not null in that 
case? Perhaps you meant to say that requestEvent.getServerTransaction 
returns null?

Regards,
Jeroen
