a dialog is typically established between two endpoints, which are
better identified by an IP address, behind a domain can be many ip
addresses, which can result on requests within dialog being routed to a
different server. If you have only one, set the server_address parameter
to presence module to what you want:

  -

You can also change the condition so it uses (uri==myself ||
is_uri_host_local()).

Cheers,
Daniel
