Function 225: PRI pilot number programming
Note: This feature is accessible only if Function 2135 (page E.15) or Function 2145 (page E.24) is enabled.
Every call on a PRI span or SIP trunk is sent with the called number in the setup message. This means you
can determine whether to use a number as a pilot number or as a DID number. Pilot numbers are a means of
routing a company’s primary published phone number differently from a DID. As noted in “Translation tables”
in “System capacities” (page B.1), the IP Server 900 has different limits on pilot entries, depending on dialing
plan and whether SIP is in use. This is important, because the dynamic channel allocation prevents you from
routing based on channel.
Pilot numbers can be routed to an ID branch, department, extension, mailbox, or the internal ESI Fax over e-
mail server. This varies from DIDs in that, when a DID number is routed to an extension, it is considered
answered and follows the busy/no-answer routing of the extension; but, with pilot numbers, the call will be
routed to the extensions for live answer for the designated number of rings, then can be routed to an ID
branch in the event of busy/no-answer. If the PRI span or SIP trunk is used for outgoing calls, pilot table entry
1 is used for outgoing Caller ID, as well. Because of this, pilot number entry 1 should always be programmed
with 10 digits.
Note: An extension’s Caller ID number setting (see “Function 31: Extension definition and routing,” beginning
on page F.2) overrides the pilot number’s Caller ID information set here.
Max Channels value
Max Channels is the maximum number of channels that can be used simultaneously for incoming calls to
a particular pilot number. Incoming calls to that pilot number are rejected (CO plays busy signal) when the
Max Channels value is exceeded for the pilot number. Max Channels is applicable only to incoming calls.
Notes: This setting works only if the digits in the pilot number entry exactly match the digits that the PRI or
ITSP carrier sends in its messaging.
The sum of maximum channels of any SIP pilot number must not exceed 24.
The sum of maximum channels of any PRI pilot number must not exceed 23.
To program the pilot number translation table:
1. Either enter a pilot number or, to select a previously entered number, press a scroll key. Here, the entry
is 52.
PILOT #52
>
When done, press #.
Range: 1–100.
2. The system prompts you to enter a name for this pilot number:
PILOT #52
N: >
Enter a name (or leave it as it is). Then, press #. (For detailed help with this step, press HELP or see
“Entering alphanumeric characters,” page C.2).
3. The system displays the maximum allowable channels for this pilot number:
PILOT #52
MAX CHANNELS 23
Enter a new value (or leave the setting as it is). Then, press #.
Range: 1–24 (SIP) or 1–23 (PRI). Default: 24 (SIP) or 23 (PRI).
