Configure NEC UX5000 w/ Nuvox

SIP Trunking Service

(2)

Configure a NEC PBX

Goal

Provide a reference to NEC Solutions Providers and customers for configuring a NEC UX5000 to connect to a Nuvox SIP Interconnect utilizing a static configuration.

The different devices can be configured in various configurations depending on your VoIP solution. This document covers the standard supported configurations.

Prerequisites

SIP trunking information provided by Nuvox ∞ Primary, SIP proxy server IP address

∞ Numbering Plan, if applicable for Point-to-Point connection. ∞ Trunking DID(s):

o The DID(s) are forwarded to the Public WAN IP address(s), DNS or DNS SRV records of the PBX. NEC UX5000:

∞ UX5000 CCPU F/W Version 2.50J or Higher ∞ VoIP Daughter Board

∞ SIP Trunking License ∞ Digital, IP, and TDM terminals References:

∞ NEC UX5000 Networking Manual

NEC UX5000 Setup

Follow the UX5000 Feature and Programming Manuals and/or Networking Manual for more detailed information on feature-specific settings.

The following are PC Programming images taken from an active UX5000 while interfaced with Nortel SIP Service. This document will provide guidance for a Static SIP Trunk Configuration on the UX5000 communications server. The images which are provide should be used only as a guide. For network specific information consult your Network Administrator and Internet Telephony Service Provider

.

Blade Configuration

Confirm the UX5000 prerequisites have been met, observe the blade configuration Central Processor is equipped with MEMDB and 32VOIPDB (the VOIPDB size will determine the number of SIP Trunks that may be supported.

(6)

CCPU Network Setup

Set IP address

Set VOIPDB Configuration Set the Subnet Mask

(7)

VOIPDB Configuration

Configure the number of physical ports trunk type which will be set as “SIP” trunks

(8)

VOIPDB DSP Resource Selection

It is recommended practice to select “Commonly used for both IP extensions and trunks” This configuration should be applied to all SIP Trunks.

(9)

SIP System Information Setup

10-28-01: This is the Domain name that the UX5000 resides in. 10-28-02: This is the Host Name of the UX5000 in the domain. 10-28-03: Leave set to UDP

10-28-04: User ID in the SIP Invite Setup message. It is also used for outbound caller ID information if no information is assigned in commands 21-17, 21-19, 15-16, 14-12, and 10-36. Bandwidth.com defaults to E.164 format if using this setup in a UX5000 you will need to ask that 10 digit dialling by set in the Bandwidth.com network.

A call can not be completed across the span if there is no outbound CID info at all. The reason for this is: the “from” and “display” portion of the invite message would be blank and it would not know where the call originated from.

Initial Testing and Troubleshooting

Initial Test Plans:

If you run into an issue with any of these tests, consult the troubleshooting chart below:

1. Test an Outbound call to a Local Number. Check for Ringback, 2-way Audio, and Quality.

2. Test an Outbound call to a Long Distance Number. Check for Ringback, 2-way Audio, and Quality. 3. Test an Outbound call to an International Number. Check for Ringback, 2-way Audio, and Quality. 4. Test a Long Outbound call past 15 minutes.

5. Test multiple call concurrencies on Outbound calls. Set up multiple calls to PSTN. 6. Test an Outbound Call to Operator “0”.

7. Test an Outbound Call to Directory Assistance “411”.

8. Test a 911 Call. (PLEASE IDENTIFY TO THE OPERATOR THAT THIS IS A TEST!!!!!) 9. Test an Inbound call to an internal DID. Check for Ringback, 2-way Audio, and Quality. 10. Test an Inbound call to Auto-Attendant. Check DTMF and Audio Quality.

11. Test Transferring calls off-site.

12. Test an Outbound call to an Auto-Attendant and verify DTMF. Troubleshooting Guide:
