Thanks Alex and Kaufman,
As you said there is an element of db blocking for accounting, but I don't see the
same impact when the INVITE goes through and sets the accounting flags.
I will look to disable accounting and see if it improves things. If not, I will have a
look at benchmark to try and pin it down. It is not causing any noticeable delay in the
clearing down of the call to the end users but I want to try and optimise the cleardown if
possible.
Once I have tested this I will report back. Thanks for your assistance.
