I am not sure what version of LCS that you are using or what client you are
using. I will respond for LCS 2003 simply because there was a question,
similar to this, in the boards earlier today.
Windows 5.1 can be used, unsecured, with TCP as I understand it. Most of
the organizations I have worked prefer to use TLS over TCP on 5061 or 443,
rather than just opening flat TCP over 5060. The kicker is generally
getting the certificates setup for TLS.
Another thing to remember is that you will have to change authentication
from Kerberos to NTLM and Keberos or NTLM. Clients outside the firewall
generally can't talk to the KDC and be granted a Kerberos ticket. My
understanding is that the Kerberos ticket request can't be encapsulated in
the SIP packet easily, but the NTLM traffic can be encapsulated.
There are several things that you may need and Microsoft has documented
these well. My response includes the basic EOUS document as well as the
ISA-specific information.
Below is the LCS 2003 Enabling Outside User Scenarios whitepaper:
