Configuring port, certificate and DNS values for an OCS 2007 R1 / R2 Edge server topology can be confusing, especially when multiple Edge servers are involved. This OCS 2007 R1/R2 Remote Access Configuration Guide was created to simplify the process:
Office Communications Server (OCS) 2007 R2 provides instant messaging (IM), presence, conferencing—and if PSTN integration is configured—voice capability for employees within your organization. To allow remote access to these features it’s necessary to install and configure one or more Edge servers.
Currently there are 2 versions of OCS deployed in production environments; the original version which is referred to in this document as OCS 2007 “R1” and the most recent version called OCS 2007 “R2”.
Between the 2 releases there are four primary Edge topologies and this document covers all of them, starting with the simplest and moving to the most complex. The focus will be on the current R2 version of OCS 2007 but configuration and operational differences between versions will be clearly defined when necessary.
The Configuration Guide is split into 3 sections:
Step 1 - Review the information in the Overview section and determine which remote access scenario matches your business requirements
Step 2 - Review the 10 to 15 pages associated with the specific scenario you want to deploy
Step 3 - Search each of the tables related to the chosen scenario replacing existing server FQDNs / IP Addresses with your production values
Step 4 - Print out the results and use it as a reference for ordering certificates, opening firewall ports and creating DNS A / SRV records
Step 5 - Optionally, use the Step by Step instructions to configure OCS for remote access if necessary
The best practice and related configuration information provided in the various sections is based on over 50 production remote access deployments but please keep in mind they are recommendations only. It is possible to configure OCS remote access many different ways but this document focuses on the approach proven to produce consistent results with a minimum of errors.

Excellent work !!! Very helpful indeed. All the common scenarios explained in full detail. Step by Step instructions are great!!
what if we have a single AD & multiple sip .. then how will we restrict remote administrators so that they can create only respective sip for respective users.
we have single AD ... and 6 differnt universities but all are on same AD... each uni has its own UPN.. how can we restrict these six universities (uni) admin .. which will connect remotely and they shud be able to make users of their respective upn only.. uni1 must not be able to mess with uni2 sip... intentionally or unintentionally ...
please guide! thanking u in advance
