Description

Served Trunk
Group

Integer
-1 (Not
Defined) or
1-100

Instant

The Trunk Group for which the device performs
registration and/or authentication to a destination IP
Group (i.e., Serving IP Group).

For Tel-to-IP calls, the Served Trunk Group is the
source Trunk Group from where the call initiated. For
IP-to-Tel calls, the Served Trunk Group is the 'Trunk
Group' defined in the 'IP to Tel / Inbound Routing'
table.

Note: for IP-to-IP call routing, this parameter must be
set to Not Defined.

Served IP
Group

Integer
-1 (Not
Defined) or
1-32

Instant

The Source IP Group (e.g., IP-PBX) for which
registration and/or authentication is performed.

Note: for Tel-to-IP call routing, this parameter must be
set to Not Defined.

Serving IP
Group

Integer
-1 (Not
Defined) or
1-32

Instant

The destination IP Group ID to where the REGISTER
requests (if enabled) are sent or Authentication is
performed. The actual destination to where the
REGISTER requests are sent is the IP address
defined for the Proxy Set associated with this IP
Group. This occurs only in the following conditions:



The parameter 'Registration Mode' is set to 'Per
Account' in the 'Trunk Group Settings' table.



The parameter 'Register' in this table is enabled.

In addition, for a SIP call that is identified by both,
Served Trunk Group/ Served IP Group and Serving IP
Group, the username and password for digest
authentication defined in this table is used.

For Tel-to-IP calls, the Serving IP Group is the
destination IP Group defined in the 'Trunk Group
Settings' table or 'Tel to IP / Outbound Routing' table.
For IP-to-Tel calls, the Serving IP Group is the 'Source
IP Group' defined in the 'IP to Tel / Inbound Routing'
table.

Note: if no match is found in this table for incoming or
outgoing calls – the username and password global
parameters, defined in the 'Proxy / Registration' are
used.

Username

String
Up to 50
chars.

Instant

Digest MD5 Authentication user name (up to 50
characters).

Password

String
Up to 50
chars.

Instant

Digest MD5 Authentication password (up to 50
characters).
