[reSIProcate] PRACK Support?

[Scott Godin]

PRACK support is NOT currently implemented.  The state machine of the
InviteSession should contain all of the states required for PRACK, but
the states have not yet been implemented.  I can't really say when it
will be completed, since I don't think anyone is currently working on
it.  

 

The stack will internally take care of retransmissions.

 

I don't anticipate that the current API's will change at all.  If you
receive a provisional response and PRACK is listed as a supported method
in the Profile and supported by the far end, then it will be used.
There will also be more scenarios when SDP offer and answer exchanges
can take place before the final response.

Subject: [reSIProcate] PRACK Support?

 

Hi All

 

Does the latest release support PRACK (RFC 3262)? The wiki documentation
says PRACK support is in progress.

 

Based on the support or non-support, I have the following questions

1.	If supported, what is the interface from DUM to the application?
Will the stack internally take care of retransmission of PRACK?
2.	If not, when is it going to be supported? What will be the
interface for PRACK support to the application

 

 

Thanks

Suresh RV
