A friendly, no-stress office phone system: named extensions (100,101…), outside callers reach you via DID/DIL, teams ring together in hunt groups, voicemail works, menus are short (“1-Sales, 2-Support”), and IT has QoS, VLAN, backups, and security dialed in.
Plan: Users 100–149, hunt groups 200–209, features 7xx. Main DID +1-555-0100 → Reception (or AA). Open hours 09:00–17:00, after-hours → voicemail.
Applies to
NEC SV9100/SL2100 via WebPro/PCPro. Phones: IP/SIP/DTL. Trunks: SIP or Analog (CO/FXO). Concepts map 1:1 across these systems.
Name an extension (what people see)
15-01: Extension Basic Setup
• Select ICM Extension → Name = “Amy”
• Apply → Save
This updates phone displays and the internal directory.
15-01: إعدادات الامتداد
• اختر الامتداد → الاسم = "Amy"
• حفظ
Change an extension number
11-02: Extension Numbering
• Select Port/Ext → New Number = 110
• Apply → Save
Stick to a simple plan: 1xx users, 2xx hunt groups, 7xx features.
11-02: ترقيم الامتدادات
• اختر المنفذ/الامتداد → الرقم الجديد = 110
• حفظ
Outbound dial (9 for outside line) & ARS
11-09: Trunk Access Code
• Access Code = 9
(tie to ARS so 9 + number routes to the correct trunk group)
Emergency: Add a dedicated code for 911/112 that bypasses prefixes and uses the primary route instantly.
Control who can call where (toll classes & override PIN)
21-04: Toll Class per Extension
21-05/21-06: Allowed/Blocked patterns per Class
21-07: Override Password (walking PIN) for supervisors
Give general staff a limited class, supervisors an override PIN.
Set the outgoing Caller ID (per extension)
21-13: ISDN/SIP Calling Party Number
• Select Extension → Set CLI digits per carrier format
• Save
Some carriers override CLI; coordinate with them if needed.
Analog trunks (CO/FXO) & analog devices (fax/SLT)
Analog Trunks:
14-01: Put ports in a Trunk Group
14-02: Trunk Type (Loop Start, DID, etc.)
14-06: Trunk Group Routing (tie to ARS/outbound)
Save
Analog Devices (Fax/SLT):
11-02: Create the SLT extension
15-01: Name it, adjust SLT options if required
Test fax send/receive
SIP trunk basics (registration & DTMF)
SIP Line (84-xx): Registrar/Proxy, Auth username/password
DTMF Method (84-35): RFC2833/Out-of-band per carrier
Line Group ID: Assign (e.g., 50:Main)
Match DTMF with your carrier or IVRs will misread digits.
Inbound routing: DIL vs DID (and overflow)
DIL (Direct In Line):
22-07: Send trunk to a single destination (e.g., Reception)
22-08: No-answer destination after a timer
DID (Direct In Dial):
22-10: Translation Table size
22-11: Translate received digits → ext/group
22-13: Assign table to trunk group
Unmatched/Vacant:
22-12: DID Intercept Ring Group for fallback
Point main number to Reception or AA; map other DIDs to Sales/Support.
Hunt groups & pickup groups
Sales Group:
Ext = 201
Members = 100,101,102
Ring = Collective (all ring)
Voicemail after 20s
Pickup Group:
23-02: Put a team in the same pickup group
Users can answer each other’s ringing phones
Auto Attendant & voicemail (InMail)
Create Open/After-Hours time mode; route DIL/DID to AA or Reception accordingly.
Record short menus: “Welcome… Press 1 for Sales, 2 for Support, or 0 for the operator.”
Enable voicemail per user/group; set timeouts (e.g., 18–22s) and email notifications if used.
Keep menus ≤3 options; always offer “0” for a human.
Phone Feature Codes (quick & safe)
Use these on a multiline set (MLT) unless noted. Exact codes can be customized by installers, but these are the factory defaults on most NEC SL1000/SL1100/SV9x00 class systems.
Auto-answer / Intercom behavior
821 → Handsfree Answerback ON (auto-answer intercom)
823 → Forced Intercom Ring (auto-answer OFF)
(While calling an extension, press 1 to toggle ring/answerback for that call)
Use 821 at a receptionist/supervisor desk (headset users love it). Use 823 for shared/open areas to prevent calls from bursting onto speaker.
Call Forward (CF)
848 → CF Immediate (All) → 848 + destination (ext/VM/outside)
844 → CF Busy/No-Answer → 844 + destination
842 → Both Ring → 842 + destination
846 → Follow-Me → set from destination phone
Tip: assign a CF-All key so users can toggle without remembering codes.
Pickup, Park & Retrieve
856 → Group Call Pickup (grab ringing call in your pickup group)
868 → Park a call (system parks to an orbit)
869 → Retrieve a parked call (then dial orbit if prompted)
Great for small teams—park once, announce on PA, and anyone can retrieve.
Station & System Speed Dial
855 → Program Station Speed Dial (one-touch or list)
#4 → Use Group/System Speed Dial (dial list code)
Use Station Speed for personal numbers; use Group/System for shared lists.
Program from the phone (assign keys, one-touch, etc.)
From a multiline telephone with permission:
Assign a feature to a spare key (Flexible Function Key)
Press Speaker → dial 851.
Press the **spare key** you want to program (its LED will flash).
Enter a **Key Code** for the function, then Speaker to save.
Examples (Key Codes)
10 → Call Forward All (Immediate)
13 → Call Forward Busy/No-Answer
14 → Both Ring (CF)
15 → Follow-Me
07 → Group Call Pickup
03 → One-Touch / DSS / Speed Key
To erase a key: Press Speaker → 852 → press the programmed key → Speaker.
Create a One-Touch key to dial an outside number
Press Speaker → dial 851.
Press the target key → enter 03 (One-Touch) → Speaker.
Press the key again → dial your route access (often 9) + number (e.g., 9 1 555 0123) → Hold/Save → Speaker.
Analog phones (SLT) quick notes
Lift handset, then dial the same service codes (e.g., 821/823, 848, 856, etc.).
Without feature keys, SLTs are limited to code dialing (no LEDs).
If you need a lot of features on SLTs, consider upgrading to a multiline set.
Printable quick-reference (post at Reception)
Internal call Dial ext (e.g., 100 → 101)
Outside line 9 + number (or your site’s access code)
Auto-answer ON / OFF 821 / 823
Call Forward All / B/NA 848 / 844 (842 Both Ring, 846 Follow-Me)
Group Pickup 856
Park / Retrieve 868 / 869
Transfer (attended / blind) Transfer → ext (announce) / Transfer → ext (hang up)
3-Way Conference Conf → dial → Conf
Voicemail VM Pilot (e.g., 700/800) then mailbox
Toll Override (LD/Intl) 875 + password + 9 + number
Program key (assign/erase) 851 / 852 (use 03 for One-Touch/DSS)
BGM / Page Zones Use assigned keys (via 851)
Group Login/Logout Use assigned key (via 851)
Happy users: button programming
On each phone template, add: Line Appearance, Park 1/2, Pickup Group, Voicemail Collect, DND Toggle, and BLF keys for teammates.
IT extras: QoS, VLAN, NTP/DNS, backups, security
QoS: Mark voice as DSCP 46 (EF); trust DSCP on switches; prioritize uplink.
Voice VLAN: Phones on a dedicated VLAN; DHCP optioning for voice if required.
NTP/DNS: Correct time = clean logs/voicemail stamps. Set system NTP and DNS.
Backups: In WebPro/PCPro, save config to your PC and keep an off-box copy (include InMail prompts).
Logging: Enable SMDR to a collector; use SNMP to watch ports/trunks.
Security: Change all defaults; restrict remote access; keep toll classes tight; use override PINs sparingly.
