Alias Names
Configuration note:
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
RAS port
Registration TTL (s)
Value
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:
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:
PRI (Private Unknown Number);
(Private Local Number (CDP)).
• H.323Identifier — alphanumeric strings representing names, e-mail addresses, etc.
Identified by the keyword
Example: The BCM is assigned a public dialed number prefix of 76, a private CDP
number of 45, and an H323 Identifier alias:
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 . Example for private networks: CDP alias = src:<DN>; UDP alias =
src:
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.
Refer to "Using CS 1000 as a gatekeeper" on page 389
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.

UDP (Private Level 1 Regional Number (UDP));
NAME:
Alias Names: PUB:76, CDP:45,
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.
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.
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.
