With the news that Ericsson LG will be discontinuing the eMG80 PBX, I'm publishing some notes I made years ago with the hopes that someone finds them useful. I'll publish similar notes for other manufacturers at later dates.

# Hardware

## DIP switches
* 1 and 2 off in normal operation
* 2 on during boot defaults the system

## Port wiring
* Analogue extension RJ11: Pins 3 and 4 (innermost 2)
* Digital extension RJ11: Pins 2 and 5 (nextmost 2)
* Line cord RJ45: Line 1, Pins 1 and 2. Line 2 Pins 5 and 6
* Digital extension RJ45: Pins 4 and 5 (innermost 2)
* BT>RJ45 line cord conversion: Pins 2 and 5 > Pins 4 and 5 (innermost 2)

# Software

## Default details
The default IP address of the system on first boot is `10.10.10.2`. The default login details are `admin : 1234`.

## Network ports

## Music on hold filenames
File format specifics [described here](/ffmpeg-audio-conversions-for-pbx/).
* eMG80: 71.wav
* UCP100: 201.wav

## COS lockdown steps
* PGM 160 > Remote VM Access: Off
* PGM 160 > VM Notify: Disable
* PGM 160 > Remove VM Forward Access: Off
* PGM 127 > 101 to *last extension number* > VSF Access: Disable

* PGM 226 > 999, 911, 912, 111, 112

## IP authenticated SIP trunk setup
Assuming remote setup, using an IP phone for testing
* PGM 102 > Firewall IP Address - *wanipaddress*
* PGM 113 > *ipphonestation* - Station CLI 1 - DDI number minus leading zero
* PGM 132 > 13/2401 - Firewall IP Address & Router IP Address - Copied from PGM102
* PGM 133 > *siptrunknumbers* - Domain & Proxy Server Address - *sipserveraddress*, Domain Acceptance - Domain Only
* PGM 140 > *siptrunknumbers* - CO Type - DDI, CO/IP Group - 2
* PGM 145 > *siptrunknumbers* - DID Conversion Type - Modify Using Flexible DID Conversion Table
* PGM 151 > *siptrunknumbers* - CLIP Table Index & COLP Table Index - Station CLI
* PGM 160 > CO Line Choice - ROUND
* PGM 231 > *ddilast3digits* - *ipphonestation*

* For CLIR: PGM 133 > Privacy(CLIR) Presentation - Privacy: id & Anonymous & P-Preferred-ID

## LCR prefix area code
* PGM 220 > LCR Access Mode: Loop & Direct CO LCR
