How to Factory Reset Polycom VVX 300 VOIP Phones

This is from memory and my notes, and may be incomplete, or have errors, but regardless…

Power Cycle the phone.

Hit Cancel on Boot screen (you will see an option to cancel by hitting one of the menu buttons while it’s booting).

Press 1+3+5, hold them down. NOTE: there is also a function where you can hit 3+5+7. One of these is the right one. I think it’s 1+3+5, but if that doesn’t bring you to a password prompt, try 3+5+7.

The password is the mac address. That is the easy part. The mac is on the phone on a sticker. The hard part is that you must enter letters in lower case. You can’t preview the letters, and since you have only a number pad, you have to understand how these interfaces typically work.

What there is, is a small icon on the menu that lets you change from numbers to upper case letters, to lower case letter, then back to numbers. So in order to change from number to lower case, you have to hit that button on the screen. And also, if you change back to numbers, you must hit the button again. So sometimes you might have to blindly hit a few keys. E.g. cat would be 1+1+1 (for c), a short pause, then 1 (for a), then whatever t is. But you can’t see the a going from a to b to c. It’s all hidden behind hashmarks for “security”. So you are blind and must press the buttons in the correct sequence. Horrible design, but the idea must be that only IT guys will ever work with the interface. They should be used to getting the short end of the administration stick, so will not be surprised. I was not be surprised, to be honest, just disappointed.

Configuration for Verizon VOIP

After you put the password in, you can factory reset, or possibly it does a factory reset automatically. Now the VOIP phone is back to its base mode. When it reboots you can now access the admin section, with the password “456”. For Verizon’s voip, the settings are:
Go somewhere in the network menus (I didn’t note where).

Enable ZTP
Server type - HTTPS

Then I believe a reboot.

I purchased a surplus Rayovac PS133 Nicad AA/AAA battery charger, but had trouble getting it to work. The LEDs which indicate that it is actively charging would not light up. After looking around a bit inside, I made the following changes: 1) Add a resistor to the LED for the first battery, so you know when 1 is connected (glows at half brightness). 2) Add some solder to the positive connectors, so that the batteries can make contact. Without the solder or some type of material on the positive contacts, the batteries would not make contact with the case on. My particular batteries are Panasonic N-700AAC Nicad batteries.. See the following video.

PrestaShop, Docker, SSL, Nginx Reverse Proxy

This is a common problem for Prestashop as viewed on the https://github.com/PrestaShop/docker and Prestashop forums. Here’s some configurations I found necessary to handle this. I was able to get it working. First off, there are a few files you need to keep in mind: The DB has two tables: ps_shop_url, ps_ssl_enabled, which must be edited manually. The nginx.conf must have the right settings (they can be the same as a wordpress reverse proxy, so start there). And it was necessary to set $_SERVER[‘HTTPS’] = ‘on’; in the prestashop_root/config/ folder under one of the defines. I used defines_custom.inc.php. I understand this is not best practice, but I got it to work. Interested users should research where it’s best to put custom edits for Prestashop. Here’s quickly some more notes: nginx.conf:# shopping site redirectserver {#server tokens hides the nginx identifying itselfserver_tokens off;server_name shop.mysite.com;listen 80; location ^~ /.well-known {alias /var/www/html/.well-known/;#autoindex on;}location / {##** nginx redirect ALL http requests to https ** ##return 301 https://$server_name$request_uri;#from gist mentioned below#rewrite ^ https://$host$request_uri? permanent;}}server {#server tokens hides the nginx identifying itselfserver_tokens off;server_name shop.mysite.com;#listen 80;listen 443 ssl;ssl_certificate /etc/letsencrypt/live/mysite.com/fullchain.pem;ssl_certificate_key /etc/letsencrypt/live/mysite.com/privkey.pem;location / {proxy_redirect off;proxy_pass http://prestashop;#these were from wp, but not usable here, according to:#https://gist.github.com/chroriginal/8d8ea7d284bcc42055a6ba18c04aeccfproxy_set_header X-Real-IP$remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header Host$host;#this was from gist, but doesn't work.#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;#proxy_set_header Host$http_host;#proxy_set_header X-Forwarded-Proto https;#from git issues trackerproxy_connect_timeout 300;proxy_send_timeout 300;proxy_read_timeout 300;send_timeout 300;}}

Here is the docker-compose.yml:

version: '3'

services:
nginx:
image: nginx:latest
container_name: production_nginx
volumes:
- ./nginx.conf:/etc/nginx/nginx.conf
- /etc/letsencrypt/:/etc/letsencrypt/
- ./webroot/:/var/www/html/
ports:
#be careful with these. Port 80 on container side must match nginx listen port. the host side port, is only for the docker proxy.
- 80:80
- 443:443

restart: always
#    command: [nginx-debug, '-g', 'daemon off;']

db_prestashop:
image: mysql:5.7
environment:
- MYSQL_USER=xxxxxx
- MYSQL_DATABASE=prestashop
volumes:
- ./db_data_presta:/var/lib/mysql
- ./db_conf_presta:/etc/mysql/
restart: always

prestashop:
depends_on:
- db_prestashop
image: 'prestashop/prestashop'
volumes:
- ./presta_root:/var/www/html/
environment:
- DB_SERVER=db_prestashop
- VIRTUAL_HOST=https://URLHERE
- VIRTUAL_PORT=80
- PS_DOMAIN=https://URLHERE
- DB_NAME=prestashop
- DB_USER=xxxxxx
- DB_PASSWD=xxxxxx
restart=always


I don’t believe the DB_NAME or DB_USER variable is used in docker for prestashop. DB config is done at installation. Virtual host likewise, may not be necessary.

use prestashopSELECT NAME, VALUE FROM ps_configuration WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');UPDATE ps_configuration SET VALUE = '1' WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');SELECT NAME, VALUE FROM ps_configuration WHERE NAME IN ('PS_SSL_ENABLED', 'PS_SSL_ENABLED_EVERYWHERE');

Also, one other change on the DB. You should ensure that your shop URL is set to be something like URL.com
You do NOT want https://URL.com in either domain or domain\_ssl in ps\_shop\_url

mysql> select * from ps_shop_url;

Solution

In gentoo, the mupdf profile  in /etc/firejail/has

# Firejail profile for mupdf

# This file is overwritten after every install/update
# Persistent local customizations

read-only ${HOME} However, the private-etc fonts will cause this error. This was found by brute force troubleshooting (delete entries from profile, until it works). Comment it out, and MuPDF should display correctly. now you will get:$ firejail mupdf sample.pdf
