Just a quickie and not really Apollo related but it took me a while to figure out how to implement Sipgate-Team trunks into Freeswitch, since the wiki only covers the single user sipgate accounts:

<include>
 <gateway name="sipgate-team-trunk">
  <param name="proxy" value="sipconnect.sipgate.de"/>
  <param name="outbound-proxy" value="sipconnect.sipgate.de"/>
  <param name="register-proxy" value="sipconnect.sipgate.de"/>
  <param name="username" value="1234567t0"/>
  <param name="auth-username" value="1234567t0"/>
  <param name="from-user" value="1234567t0"/>
  <param name="from-domain" value="sipconnect.sipgate.de"/>
  <param name="password" value="654321"/>
  <param name="ping" value="25"/>
  <param name="context" value="public"/>
  <param name="register" value="true"/>
  <param name="register-transport" value="udp"/>
 </gateway>
</include>

<X-PRE-PROCESS cmd="set" data="default_provider=sipgate-team-trunk"/>

In order to get valid outgoing CID's sipgate needs another header:

<include>

  <extension name="sipgate-outbound">
    <condition field="destination_number" expression="^(\d+)$">
      <action application="set" data="effective_caller_id_number=${outbound_caller_id_number}"/>
      <!-- <action application="set" data="effective_caller_id_name=${outbound_caller_id_name}"/> -->
      <action application="set" data="sip_h_P-Preferred-Identity=sip:${outbound_caller_id_number}@sipconnect.sipgate.de"/>
      <!-- <action application="bridge" data="sofia/gateway/${default_gateway}/$1"/> -->
      <action application="bridge" data="{sip_cid_type=pid}sofia/gateway/${default_gateway}/$1"/>
    </condition>
  </extension>

</include>

Where ${outbound_caller_id_number} is defined in the directory as 491234567890 without a + or 00.
