Mediant 3000
Parameter Description
[IPGroup_MediaEnhance
mentProfile]
By default, no value is defined (None).
For configuring Media Enhancement Profiles, see ''Configuring Media
Enhancement Profiles'' on page 316.
Bandwidth Profile
[IPGroup_BWProfile]
Assigns a Bandwidth Profile rule.
By default, no value is defined (None).
For configuring Bandwidth Profiles, see ''Configuring Bandwidth Profiles''
on page 313.
Always Use Src Address
[IPGroup_AlwaysUseSour
ceAddr]
Enables the device to always send SIP requests and responses, within a
SIP dialog, to the source IP address received in the previous SIP
message packet. This feature is especially useful in scenarios where the
IP Group endpoints are located behind a NAT firewall (and the device is
unable to identify this using its regular NAT mechanism).
[0] No = (Default) The device sends SIP requests according to the
settings of the global parameter, SIPNatDetection.
[1] Yes = The device sends SIP requests and responses to the
source IP address received in the previous SIP message packet.
For more information on NAT traversal, see ''Remote UA behind NAT''
on page 169.
Contact User
[IPGroup_ContactUser]
Defines the user part of the From, To, and Contact headers of SIP
REGISTER messages, and the user part of the Contact header of
INVITE messages received from this IP Group and forwarded by the
device to another IP Group.
By default, no value is defined.
Notes:
The parameter is applicable only to Server-type IP Groups.
The parameter is overridden by the ‘Contact User’ parameter in the
Account table (see ''Configuring Registration Accounts'' on page 363).
Local Host Name
[IPGroup_ContactName]
Defines the host name (string) that the device uses in the SIP message's
Via and Contact headers. This is typically used to define an FQDN as
the host name. The device uses this string for Via and Contact headers
in outgoing INVITE messages sent to a specific IP Group, and the
Contact header in SIP 18x and 200 OK responses for incoming INVITE
messages received from a specific IP Group. The Inbound IP Routing
table can be used to identify the source IP Group from where the INVITE
message was received.
If the parameter is not configured, these headers are populated with the
device's dotted-decimal IP address of the network interface on which the
message is sent.
By default, no value is defined.
Note:
To ensure proper device handling, the parameter should be a valid
FQDN.
Used By Routing Server
used-by-routing-server
[IPGroup_UsedByRouting
Server]
Enables the IP Group to be used by a third-party routing server for call
routing decisions.
[0] Not Used (default)
[1] Used
