Name

Description

NR Group

Use this field to assign a network region group to the network region. You can enter a value from: 1 to 2000 for large systems. 1 to 250 for small systems.

Note:

Do not leave the field blank. You can assign multiple network regions to the same network region group.

Region

Network Region number, 1–2000.

Location

Blank or 1–2000.

If you leave the field blank, the system obtains the location from the PROCR that the endpoint is registered through. The system can also get the location from the gateway through which the endpoint is registered. The setting for the location field applies to IP telephones and softphones.

Name

The name of the region. Enter a character string up to 20 characters.

Authoritative Domain

The network domain of the server.

Stub Network Region

The network region that is a core network region or a stub network region. For network regions 251 to 2000, this field is a read-only field with a default value n.

If you are creating a stub network region, you must enter more information on page 4, in the dst rgn field. Enter the number of the destination core network region that directly connects with this stub network region.

Note:

To convert a core network region to a stub network region, ensure that the core network region is connected with only one core network region. A stub network must have only one direct connection with a core network.

MEDIA PARAMETERS

Codec Set

Specifies the codec set assigned to a region. Enter a value between 1-7. The default value is 1.

Note:

Codec sets are administered on the CODEC Set screen. See IP CODEC sets.

UDP Port-Min

Specifies the lowest port number to be used for audio packets. Enter a value between 2-65406. The default is 2048.

Note:

This number must be twice the number of calls that must be supported plus one, must start with an even number, and must be consecutive. The minimum range is 128 ports.

Caution:

Do not use the range of well-known or IETF-assigned ports. Do not use ports below 1024.

UDP Port-Max

Specifies the highest port number to be used for audio packets. Enter a value between 130-65535. The default value is 65535.

Caution:

Intra-region IP-IP Direct Audio

Enter y: To save on bandwidth resources and improve sound quality of voice over IP transmissions.

Enter native (NAT): If the IP address from which audio is to be received for IP-to-IP connections within the region is that of the IP telephone/IP Softphone. Ensure that the IP address has not been translated by NAT. IP telephones must be configured behind a NAT device before this entry is enabled.

Enter translated (NAT): If the IP address from which audio is to be received for IP-to-IP connections within the region is the address with which a NAT device replaces the native address. IP telephones must be configured behind a NAT device before this entry is enabled.

Inter-region IP-IP Direct Audio

Enter y to save on bandwidth resources and improve sound quality of voice over IP transmissions.

Retry upon RSVP Failure Enabled

Specifies whether to enable retries when RSVP fails. Enter y or n. This field only displays if the RSVP Enabled field is set to y.

RSVP Profile

This field only displays if the RSVP Enabled field is set to y. You set this field to what you have configured on your network:

  • guaranteed-service makes a limit on the end-to-end queuing delay from the sender to the receiver. This setting is the most appropriate setting for VoIP applications.

  • controlled-load, a subset of guaranteed-service, provides for a traffic specifier but not the end-to-end queuing delay.

RSVP unreserved (BBE) PHB Value

Provides scalable service discrimination on the Internet without per-flow state and signaling at every hop. Enter the decimal equivalent of the DiffServ Audio PHB value, 0-63. This field only displays if the RSVP Enabled field is set to y.

Note:

The per-flow state and signaling is RSVP. When RSVP is not successful, the BBE value is used to discriminate between Best Effort and voice traffic that has attempted to get an RSVP reservation, but failed.

ALTERNATIVE NETWORK ADDRESS TYPES

ANAT Enabled

Use this field to control the call processing behavior to send Alternative Network Address Types (ANAT) offer system wide.

The valid entries are:

  • y: Communication Manager sends ANAT offer irrespective of the ip-network-region system wide setting.

  • n: Communication Manager does not send ANAT offer irrespective of the ip-network-region system wide setting.

INTER-GATEWAY ALTERNATE ROUTING/DIAL PLAN TRANSPARENCY

If Inter-Gateway Alternate Routing (IGAR) is enabled for any row on subsequent pages, the following fields for each network region must be administered to route the bearer portion of an IGAR call.

Conversion to Full Public Number - Delete

  • Valid entry: 0 to 7

  • Usage: The digits to delete.

Conversion to Full Public Number - Insert

  • Valid entry: 0 to 13 or blank

  • Usage: The number of digits to insert. International numbers should begin with plus (+). The Inter-Gateway Alternate Routing (IGAR) and Dial Plan Transparency (DPT) features convert the plus (+) digit to appropriate international access code when starting the trunk call.
    Note:

    The optional plus (+) at the beginning of the inserted digits is an international convention indicating that the local international access code must be dialed before the number.

Dial Plan Transparency in Survivable Mode

The valid entries are:

  • y: Enables the Dial Plan Transparency feature when a gateway registers with a Survivable Remote Server (Local survivable processor), or when a port network registers with a Survivable Core Server (Enterprise Survivable Server).

  • n: Default is n.

Incoming LDN Extension

An extension used to assign an unused Listed Directory Number for incoming IGAR calls.

Maximum Number of Trunks to Use for IGAR

It is necessary to impose a limit on the trunk usage in a particular port network in a network region when Inter-Gateway Alternate Routing (IGAR) is active. The limit is required because if there is a major IP WAN network failure, it is possible to use all trunks in the network region(s) for IGAR calls.

  • Valid entry: 1 to 999, or blank

  • Usage: The maximum number of trunks to be used for Inter-gateway alternate routing (IGAR).

BACKUP SERVERS IN PRIORITY ORDER

Lists the backup server names in priority order. Backup server names should include Survivable Remote Server names and Survivable Core Server names. If you are using the Processor Ethernet, the backup servers list must include the survivable core PE address else the phones will not register to the survivable core during a failure. Any valid node name is a valid entry. Valid node names can include names of Customer LANs, ICCs, Survivable Core Servers, and Survivable Remote Servers.

H.323 SECURITY PROFILES

Permitted security profiles for endpoint registration in the network region. You must enter at least one security profile. Otherwise, no endpoint will be permitted to register from the region.

The valid entries are:

  • challenge: Includes the various methods of PIN-based challenge and response schemes in current use. This is a relatively weak security profile.

  • pin-eke: The H.235 Annex H SP1

  • strong: Permits the use of any strong security profile. The H323TLS profile is the strongest security profile in Communication Manager.

  • any-auth: Includes any of the security profiles.

  • H323TLS: Communication Manager apples this security profile when the network region of an H. 323 phone is administered with H323TLS or Strong security profiles. Also, Communication Manager and the endpoint negotiate by using the H323 TLS profile. H323TLS profile sends H.323 signaling messages through a TLS-encrypted channel.

Allow SIP URI Conversion

Administers whether or not a SIP URI should be permitted to change. Degrading the URI from sips//: to sip//: might result in a less secure call. This is required when SIP SRTP endpoints are allowed to make and receive calls from endpoints that do not support SRTP.

The valid entries are:

  • y: Allows conversion of SIP URIs. Default is y.

  • n: No URI conversion. Calls from SIP endpoints that support SRTP made to other SIP endpoints that do not support SRTP will fail. However, if you enter y for the Enforce SIPS URI for SRTP field on the signaling group screen, URI conversion takes place independent of the value set for the Allow SIP URI conversion field on the IP Network Region screen.

TCP SIGNALING LINK ESTABLISHMENT FOR AVAYA H.323 ENDPOINTS

Near End Establishes TCP Signaling Socket

Indicates whether Communication Manager (the near end) can establish the TCP socket for H.323 IP endpoints in this network region.

The valid entries are:

  • y: Communication Manager determines when to establish the TCP socket with the IP endpoints, assuming the endpoints support this capability. This is the default.

  • n: The IP endpoints always attempt to set up the TCP socket immediately after registration. This field should be disabled only in network regions where a nonstandard H.323 proxy device or a non-supported network address translation (NAT) device would prevent the server from establishing TCP sockets with H.323 IP endpoints.

Near End TCP Port Min

  • Valid entry: 1024 to 65531

  • Usage: The minimum port value used by the processor Ethernet when establishing the TCP signaling socket to the H.323 IP endpoint. The range of port number must be at least 5 (Max-Min+1). Default is 61440.

Near End TCP Port Max

  • Valid entry: 1028 to 65535

  • Usage: The maximum port value to be used by the processor Ethernet when establishing the TCP signaling socket to the H.323 IP endpoint. The range of port number must be at least 5 (Max-Min+1). Default is 61444.

AGL

The valid entries are:

  • 0 to 16: Communication Manager uses the numeric value of gatekeeper addresses.

  • all: Communication Manager includes all possible gatekeeper addresses in the endpoint's own network region and in any regions to which the endpoint's region is directly connected.

  • blank: The administration field is ignored.

codec-set

  • Valid entry: 1 to 7, pstn, or blank

  • Usage: The codec set used between the two regions. This field cannot be blank if this route through two regions is being used by some non-adjacent pair of regions. If the two regions are disconnected at all, this field should be blank.

IGAR

Allows pair-wise configuration of Inter-Gateway Alternate Routing (IGAR) between network regions.

The valid entries are:

  • y: Enables IGAR capability between this network region pair. Default for a pstn codec set.

  • n: Disable IGAR capability between this network region pair. Default, except for a pstn codec set.

  • f: Forced. Moves all traffic onto the PSTN. This option can be used during initial installation to verify the alternative PSTN facility selected for a network region pair. This option can also be used to temporarily move traffic off of the IP WAN if an edge router is having problems or an edge router needs to be replaced between a network region pair.

Intervening-regions

Allows entry of intervening region numbers between the two indirectly-connected regions.

  • Valid entry: 1 to 250

  • Usage: Up to four intervening region numbers between the two indirectly-connected regions.
    Note:

    Indirect region paths cannot be entered until all direct region paths have been entered. In addition, the order of the path through the regions must be specified starting from the source region to the destination region.

Mtce

The valid entries are:
  • t: This is a test-only option. Inter-region connectivity testing is performed for the network region pair by using a simple PING sent between entities in each network region. If a test fails, only an error is added to the system error log. IP media connections between the region pair are never blocked. The testing is done at the rate of not more than once per 5 minutes.

  • m: This is a measurement based option. Inter-region connectivity testing is performed by a continuous set of PINGs sent between entities in each network region. The Ping Test Interval (sec) and Number of Pings Per Measurement Interval fields control the rate of testing. The Roundtrip Propagation Delay (ms) and Packet Loss (%) thresholds control success or failure. If the, test measurements exceed the administered thresholds; future IP media connections between the network region pair will be blocked.

  • d: No testing is performed for the network region pair.

src rgn
