According to some articles in the Internet, 15000 users is a big number
when Asterisk handles SIP registrations. That is why I planned to use
OpenSIP for SIP registrations.

In our architecture, two instances of OpenSIP and three instances of
Asterisk will handle the load -- both signaling and media. hardware wise,
we will be using 3 Nos. of DL 380 servers. Another one is used for
redundancy.

Yes, I was asking if multi tenancy is possible with Asterisk PBX?

For Fax, we will be using Asterisk as a mediator between Fax terminals and
SBC. That is Asterisk itself does not handle the RTP stream for Fax. It is
just proxying the SIP signals for Fax. Do I need to but Fax licence?
