You??™ll need a certificate issued by a public CA for federation and public IM
connectivity; also, keep in mind that public IM connectivity is going to require an
additional license.
If you are considering using voice, you need to know what to do in case of power,
network, or telephone service outages. Remember than enterprise voice depends on server
availability and voice client and hardware operability. You should also consider a secondary
or backup method of contacting emergency services. Also remember that neither OCS 2007
nor any of its components provide a caller??™s physical location to emergency services when a
caller dials emergency services. This may be required in some states or locations.
Things you should keep in mind when considering Web conferencing are fragmentation
and virus scanning. You need to defrag the drives where meeting content is located from
time to time. This is considered a best practice by Microsoft and just plain common sense
by some of the rest of us. You also shouldn??™t run real-time antivirus scanning on the
shares where meeting content, meeting content metadata, and meeting compliance data is
stored. This can negatively impact performance for Web conferencing. Microsoft recommends
scanning for viruses only when the server has little or no load and that antivirus protection
be enabled on client computers at all times. Again, some might just call this common sense.
Edge servers have their own concerns. Face it. The biggest concern is that edge servers
just don??™t scale well.
