NEC

How Voice Logica connects

The NEC registers its SIP trunks to Voice Logica (way 1) in registration mode. Voice Logica creates the trunk and gives you a server, a username and a password. Programming is in PCPro or WebPro; the SL2100, SL1100 and SV9100 use the same program numbers.

• Calls the NEC sends out on the Voice Logica trunk group are answered by the AI agent.
• The agent transfers callers back with the extension number; DID translation (22-11) rings the extension.

Before you start

• IP trunk licences: SL2100 includes 4 SIP trunks (more with licences); SV9100 includes 4; SL1100 needs them activated (Feature Activation). A Warm transfer uses two trunks until it connects.
• 10-40 IP trunk availability on, with the port count. SL1100: 10-03 VoIP card = SIP, 10-19 DSP for IP trunks. SV9100: DSP resources in 10-54, trunks in 10-68.

1. Create the connection in Voice Logica

Telephony - Trunks - Connect your PBX, pick NEC and the agent. Keep the dialog open until it says Connected.

2. Program the SIP trunks

1. 10-28 SIP System Information: Domain Name = the server, Host Name = the server, Transport UDP, User ID = the username.
2. 10-29 SIP Server Information: Outbound Default Proxy on, Proxy = the server, port 5060, Registrar = the server, port 5060, Register Mode = Manual, Register Sub Mode = off.
3. 10-30 SIP Authentication: User Name = the username, Password = the password.
4. 84-13 SIP Trunk CODEC: G.711 Type = A-law, DTMF = RFC2833 (SV9100: 84-34-01, payload 101).
5. 84-14: Called Party Info = Request URI.
6. Upload to the system; reset if PCPro asks.

3. Send calls to the agent

Put the Voice Logica trunks in their own trunk group (14-05) with an access code (11-09), or route a code through LCR (26-02 / 26-05). For a number or after-hours calls, forward that destination to a number dialled on that group.

4. Let the agent transfer back to extensions

22-02 = DID on the Voice Logica trunks, 22-09 receive digits, and 22-11 DID translation: map each number the agent sends (for example 201) to the extension. Then, in Voice Logica, add each extension as a transfer destination (External with the number, or a User with that extension) and use Warm transfer.

5. Check it works

• The dialog says Connected.
• Dial the trunk-group code: the call appears in Calls.

Good to know

• In registration mode, each extension’s 21-19 Calling Party Number must be the registered number; with Register Sub Mode on, only calls to that number come in.
• SIP dialling is en-bloc: the interdigit timer 21-01-03 decides when the number is sent.
• Behind NAT: 10-12-06 / 07 and 10-29-21 (NAT settings). Turn off SIP ALG.
