Trunks
To handle the traffic between the CS 1000 and the Office Communications
Server 2007, you must configure sufficient SIP trunks and PCAs . The
number of additional SIP trunks needed is determined by:
Determine the number of SIP trunks required by multiplying the number of
OC 2007 clients that use the SIP Gateway feature by the percentage of
users you expect on the phone at any time.
For example, 100 Office Communicator SIP Gateway users x 10% on the
phone at a time = 10 additional SIP trunks.
The percentage of users on the phone is decided by standard practice and
the environment involved (For example, Call Center or Normal Office).
PCA trunks are required for each Office Communicator user that uses the
Twinning (for SIP Gateway) feature.
SIP access port
