Figure 11: ShoreTel Server TAPI Communications
Distributed Routing Service (DRS)
DRS on each server provides routing information when switches cannot route the call in the local site
and require intersite call routing information. ShoreTel enhanced SIP protocol is used for
communications between the switch and DRS. (See Figure 12 on page 40.)
WARNING!
Never modify the TAPI properties of the ShoreTel Remote TAPI Service Provider. Modified TAPI
properties can cause ShoreTel clients or applications to fail. For information about how to test TAPI
connectivity from the client side, see Chapter 8, ShoreTel Client Applications.
