Single Edge Server

Company ABC is a small company of about 200 people located in San Francisco, uses sip.companyabc.com as its only SIP domain, and the internal Active Directory domain companyabc.local. The single Edge Server is named mcsedge and has a DNS suffix defined to match the internal domain. Company ABC plans to use a single subject alternative certificate for all external functionality. Figure 27.21 displays what the overall topology would look like. There are no high-availability requirements, and the external URLs are defined as follows:

• Access Edge Service: sip.companyabc.com

• Web Conferencing Edge Service: webconf.companyabc.com

• A/V Edge Service: av.companyabc.com

• External Web Services URL: lyncexternal.companyabc.com

• Simple Meet URL: lyncexternal.companyabc.com/meet

• Simple Dial-In URL: lyncexternal.companyabc.com/dialin
