Call Server Configuration; Configuring The Codec - Nortel 1000 Fundamentals

Call Server configuration
CS 1000 configuration involves two separate functions: Signaling Server
configuration and Call Server Configuration. All of the Signaling Server
configuration is performed in Element Manager. Most of the Call Server
configuration can also be done in Element Manager, although some can
be done at the Call Server prompt. This document assumes that you are
already familiar with how to configure a CS 1000.
In ESN networks, you must configure the correct HLOC in both LD 90
(required for ESN calls to work) and LD 15. If not, basic calling functionality
does not work. Also, the Caller ID table, Home NPA, and LOC are required
for outgoing calls to the Public network (PSTN) to correctly display the
outgoing Caller Line ID (CLID) in North America.
Package 408 is required for both Telephony Gateway and Services and
Remote Call Control. Phones need not be configured as "AST," or have
"T87A" enabled as a class of service; however, Package 408 must be added
in order for Telephony Gateway and Services to work properly.
Configuring the Codec
The Mediation Server supports the G.711 (20 milliseconds) codec. The
G.711 codec must be enforced in the network by defining only the G.711
codec on the CS 1000. If G.711 is not the only codec used, calls to voice
mail (such as CallPilot) or call conferencing bridges (such as MCS MeetMe)
do not work. The only codec supported for the short leg of a call (Mediation
Server to Call Server) is G.711 and for the long leg (Mediation Server to
Office Communications Server is RT audio.
Other codecs cannot be configured on the CS 1000, as Office Communicator
calls that tandem through the CS 1000 to other endpoints cannot be allowed
to select a codec other than G.711.
The codec is configured as described in IP Peer Networking Installation and
Commissioning (NN43001-313).
