Yes, in theses cases you have to relay on To: header value. The
problem is that not all "multiport" devices are "multi account" as
Asterisk is and you need to use aliases to send all different DIDs to
the same SIP account... some of these "multiport" devices can read the
To: value and send the call to the right place even registering only
one account.

Exactly, but a client will have (probably) just one sip account
registered, so
just one entry will appear in "location" table for him AoR.
Imagine a user "clientX@sip_proxy" using an Asterisk and registering
with:
REGISTER sip:sip_proxy SIP/2.0
To: <sip:clientX@sip_proxy>
Contact: <sip:s@ip_asterisk>
It will appear in location table with "Contact=sip:clientX@IP".
Suppose clientX has two PSTN numbers associated in a ENUM entry:
+34999000111
+34999000222
When it receives a call from PSTN to +34999000222 the INVITE
arriving to
Asterisk will be:
INVITE sip:s@ip_asterisk SIP/2.0
To: <sip:+34999000222@sip_proxy>
So the info about the real PSTN number dialed by the call
originator just
remains in the "To" header. So the client (Asterisk) must read the
"To"
header in order to have a behaviour different for +34999000111 and
+34999000222 (or adding in OpenSer other custom header containing
also dialed
number 999000222 as Juha suggests).
I can't understand how using aliases in OpenSer can help here. ¿? El Wednesday 02 April 2008 15:35:40 Jesus

You can also add multiple aliases to the same user. All INVITEs to
different aliases will be sent to the resolved user.
Yes, but after the "lookup" the RURI username will be definitively
the
username the client sent in the REGISTER's "Contact", so the INVITE
will not
change, will it?
