Networking Configuration Guide

Alias Names Alias names are comma delimited, and may be one of the following types:

E.164 — numeric identifier containing a digit in the range 0-9. Identified by the keyword

TEL: Example: the BCM is assigned an E.164 and an H323 Identifier: Alias Names:

TEL:76, NAME:bcm10.nortel.com

• NPI-TON — also referred to as a PartyNumber alias. Similar to E164 except that the

keyword indicates the NPI (numbering plan identification), as well as the TON (type of

number). Identified by one of the following keywords: PUB (Public Unknown Number);

PRI (Private Unknown Number); UDP (Private Level 1 Regional Number (UDP)); CDP

(Private Local Number (CDP)).

• H.323Identifier — alphanumeric strings representing names, e-mail addresses, etc.

Identified by the keyword

NAME:

Example: The BCM is assigned a public dialed number prefix of 76, a private CDP

number of 45, and an H323 Identifier alias:

Alias Names: PUB:76, CDP:45,

NAME:bcm10.nortel.com

• H.225 (Q.931) CallingPartyNumber (NetCentrex gatekeeper) — The NetCentrex

gatekeeper uses the H.225(Q.931) CallingPartyNumber to resolve the call originator for

billing purposes. This number must then contain a unique prefix, or location code that is

unique across all endpoints that are using the NetCentrex gatekeeper. Identified by the

keyword

src:. Example for private networks: CDP alias = src:<DN>; UDP alias =

src:<LOC><DN>. Example for public network: src:<public OLI>

Note: E164 or NPI-TON alias types are commonly used since they fit into dialing plans. A

BCM alias list should not mix these types. Also, the type of alias used should be consistent

with the dialing plan configuration. Use the same alias naming method on all BCMs within a

network.

Configuration note: Refer to “Using CS 1000 as a gatekeeper” on page 389 for specific information about

configuring the gatekeeper for H.323 trunks.Network note: If your private network contains a

Meridian 1-IPT, you cannot use Radvision for a gatekeeper.

If Gatekeeper Routed, Gatekeeper Resolved, or Gatekeeper Routed no RAS are selected under Call Signaling, enter

one or more alias names for the gateway.

Call signaling port 0-65535 Default: 1720

This field allows you to set non-standard call signaling port

for VoIP applications that require special ports.

0 = The first available port is used.

Ensure that you do not select a port that has been assigned

elsewhere in the BCM. To ensure the port is not in use, run

netstat-a from the command line.

RAS port 0-65535 Default: 0

This field allows you to set a non-standard Registration and

Admission (RAS) port for VoIP applications that require

special ports.

0 = The first available port is used.

Ensure that you do not select a port that has been assigned

elsewhere in the BCM. To ensure the port is not in use, run

netstat-a from the command line.

Registration TTL (s) Default: 60 seconds This TimeToLive parameter specifies the intervals when the

VoIP gateway sends KeepAlive signals to the gatekeeper.

The gatekeeper can override this timer and send its own

TimeToLive period.
