Use
the
add signaling group
n
command, where
n
is the number of an unused
signaling group, to create the SIP signaling group as follows:
Set the
Group Type
field to
sip
.
The
Transport Method
field will default to
tls
(Transport Layer Security).
TLS is the only link protocol that is supported for communication between
Avaya SES and Avaya Communication Manager.
Specify the Avaya S8300 Media Server (node name
procr
) and the Avaya SES
Server (node name
SES
) as the two ends of the signaling group in the
Near-
end Node Name
and the
Far-end Node Name
fields, respectively. These field
values are taken from the
IP Node Names
form shown in Step 2. For
alternative configurations that use a C-LAN board, the near (local) end of the
SIP signaling group will be the C-LAN board instead of the Media Server.
Ensure that the recommended TLS port value of
5061
is configured in the
Near-end Listen Port
and the
Far-end Listen Port
fields.
In the
Far-end Network Region
field, enter the IP network region value
assigned in the
IP Network Region
form in Step 3. This defines which IP
network region contains the Avaya SES server. If the
Far-end Network
Region
field is different from the near-end network region, the preferred codec
will be selected from the IP codec set assigned for the inter-region connectivity
for the pair of network regions.
Enter the domain name of Avaya SES in the
Far-end Domain
field. In this
configuration, the domain name is
devcon.com
. This domain is specified in the
Uniform Resource Identifier (URI) of the SIP “To” header in the INVITE
message.
The
Direct IP-IP Audio Connections
field is set to
y
.
The
DTMF over IP
field must be set to the default value of
rtp-payload
for a
SIP trunk. This value enables Avaya Communication Manager to send DTMF
transmissions using RFC 2833.
The default values for the other fields may be used.
