It's fairly standard:

<!--
    Shell provider account should work with most providers.

-->
<include>
  <user id="$${default_provider}">
    <gateways>
      <gateway name="$${default_provider}">
        <param name="username" value="$${default_provider_username}"/>
        <param name="password" value="$${default_provider_password}"/>
        <param name="from-user" value="$${default_provider_username}"/>
        <param name="from-domain" value="$${default_provider_from_domain}"/>
        <param name="realm" value="$${default_provider_from_domain}"/>
        <param name="proxy" value="$${default_provider}"/>
        <param name="expire-seconds" value="600"/>
        <param name="register" value="$${default_provider_register}"/>
        <param name="retry-seconds" value="30"/>
        <param name="extension" value="$${default_provider_contact}"/>
        <!--<param name="contact-params" value="domain_name=$${domain}"/>-->
        <param name="context" value="public"/>
      </gateway>
    </gateways>
    <params>
      <param name="password" value="$${default_provider_password}"/>
    </params>
  </user>
</include>

default_provider_register is set to true.

In the meantime I looked into the sources. If I understand them right,
proxy address is always used in REGISTER header:

sofia.c, line 1471
                        gateway->register_url =
switch_core_sprintf(gateway->pool, "sip:%s", proxy);

Probably it's incorrect as RFC 3261 says:

Request-URI: The Request-URI names the domain of the location
           service for which the registration is meant (for example,
           "sip:chicago.com").  The "userinfo" and "@" components of the
           SIP URI MUST NOT be present.

So the domain name (from-domain?) should be used there, not the proxy address.
