The next step in deployment is to prepare the Office Communications Server 2007 R2 Domain Name System (DNS) entries. The following tables show the internal and external DNS records that you need. If you are performing this walkthrough to set up Office Communications Server 2007 R2 for your company, substitute your own domain name for Litwareinc.com.
 Note: |
|---|
| The DNS names that are suggested here are examples. The DNS
record must match the fully qualified domain name (FQDN) for the
external interface(s) and that the certificate subject name or
subject alternate name (SAN) match the FQDN. The client receives
the proper DNS information for Audio/Video and Web Conferencing
from in-band provisioning after contacting and authenticating to
sip.litwareinc.com. For details, see
