Victor, Jesus,<br>thanks for the replies. <br>But the use of Remote-Party-ID/PAI (or non-use, depending on the&nbsp; terminating equipment), is a subsequent step. First I have to identify the subscriber based on the alias: the subscriber will have several of them and will send any one of them to us in the INVITE. The alias will be set in the header From, so what I need is a way to perform its lookup at table dbaliases. Then, authenticate the subscriber and finally relay the INVITE (using Remote-Party-ID/PAI or not).<br>
