<question>
<para>
Does <emphasis>dispatcher</emphasis> provide a fair distribution?
</para>
</question>
<answer>
<para>
The algoritms doing hashing over parts of SIP message don't
guarantee a fair distribution. You should do some measurements
to decide what hashing algorithm fits better in your
environment.
</para>
<para>
Other distribution algorithms such as round robin or call load
dispatching do a fair distribution in terms of delivered calls
to gateways.

<question>
<para>Is <emphasis>dispatcher</emphasis> dialog stateful?</para>
</question>
<answer>
<para>
No. Dispatcher is stateless, although some distribution algorithms
are designed to select same destination for subsequent requests of
the same dialog (e.g., hashing the call-id).
