RE: Ack not arriving

Hi Ranga,

Thanks for the help.
Unfortunately, the ACK arrives from an external source not under my control.
I receive an INVITE, reply with OK and receive the ACK.
So you are saying that the ACK MUST have a different branch id than that of
the INVITE? Is there no way around this?

Thanks,
	Gal

Hi!

The ACK branch ID is the same as the INVITE. ACKs are supposed to be 
directed to the dialog and should have a branch ID different than the 
INVITE.  Please change the branch ID for the ACK  -- or better yet, use 
Dialog.createAck as the examples do and it should work I expect.
