Subject: HELP! I can't get my Cisco CP-7960G IP hardphone to register on 
my Asterisk VoIP IP PBX SIP Server with FreePBX GUI

Good day from Singapore,

My Asterisk version: 16.13.0
My FreePBX version: 15.0.16.81

On 7 December 2020, I was able to get Bria softphone to work with my 
Asterisk PBX server successfully.

On 19 December 2020, I bought a refurbished Cisco CP-7960G IP hardphone 
for SGD$30 in Singapore. I have tried all of the following steps, but I 
simply can't get my Cisco CP-7960G IP phone to register on my Asterisk 
PBX server.

TFTP works though. My DHCP server in my pfSense firewall applaince is 
able to assign my Cisco 7960 IP phone with an IP address with DHCP 
option 66 (TFTP server). My Cisco 7960 IP phone is able to connect to my 
TFTP server on my Asterisk PBX appliance and download firmware and 
configuration files successfully. However, it simply cannot register on 
my Asterisk PBX server.

You can watch my Youtube video at

Appreciate your kind assistance.

Thank you very much.

Configuring Network Parameters
==============================

Note This section describes how to configure the basic network 
parameters that are required for the phone to operate on the network. 
For a complete list of the network parameters that you can configure, 
see the "Modifying the Phone's Network Settings" section.

The network parameters include those parameters that must be configured 
on a phone for the phone to operate in an IP network. You can configure 
the required network parameters via DHCP or manually configure them 
after you have connected the phone to a power supply.

The following parameters must be defined for your phone to establish 
network connectivity:

•Phone's IP address

•Subnet mask

•Default gateway for the subnet (use "0.0.0.0" if not required)

•Domain name

•DNS server IP address (use "0.0.0.0" if not required)

•TFTP server IP address

When configuring the network parameters of an IP phone, adhere to the 
following guidelines:

•Use 0.0.0.0 for unused IP addresses.

•You can use 0.0.0.0 for the subnet mask only if the default gateway is 
also 0.0.0.0.

•The TFTP server must have a nonzero IP address.

•The default gateway must be on the same subnet as the phone.

•The default gateway can be 0.0.0.0 only if the TFTP or DNS server is on 
the same subnet as the phone.


Note By default, DHCP is enabled on your phone. Before you can manually 
configure the network parameters, you must disable DHCP after connecting 
your phone to a power supply.

Configuring Network Parameters via a DHCP Server
================================================

If you are using DHCP to configure the network parameters, configure the 
following DHCP options on your DHCP server before you connect your Cisco 
SIP IP phone:

•dhcp option #50 (IP address)

•dhcp option #1 (IP subnet mask)

•dhcp option #3 (Default IP gateway)

•dhcp option #15 (Domain name)

•dhcp option #6 (DNS server IP address)

•dhcp option #66 (TFTP server IP address)

Reference Guide: pfSense Firewall DHCPv4 Server
Link: https://docs.netgate.com/pfsense/en/latest/services/dhcp/ipv4.html

Login to Teo En Ming's pfSense firewall appliance.

Click Services > DHCP Server.

At TFTP, click Display Advanced.

TFTP Server: 192.168.1.9

Please remember to click Save.

Then click Restart Service. You must restart the DHCP server for the 
changes to take effect.

SECTION: PERFORM FACTORY RESET ON CISCO 7960 IP PHONE
=====================================================

Because I bought an used Cisco 7960 IP phone, I must factory reset it to 
clear all previous owner's settings.

Reset the 7940 and 7960 IP Phones to the Factory Default
=========================================================

In order to perform a factory reset of a phone if the password is set, 
complete these steps:

Unplug the power cable from the phone, and then plug in the cable again.

The phone begins its power up cycle.

Immediately press and hold # and while the Headset, Mute, and Speaker 
buttons begin to flash in sequence, release #.

The Headset, Mute, and Speaker buttons flash in sequence in order to 
indicate that the phone waits for you to enter the key sequence for the 
reset.

Press 123456789*0# within 60 seconds after the Headset, Mute, and 
Speaker buttons begin to flash.

If you repeat a key within the sequence, for example, if you press 
1223456789*0#, the sequence is still accepted and the phone resets.

If you do not complete this key sequence or do not press any keys, after 
60 seconds, the Headset, Mute, and Speaker buttons no longer flash, and 
the phone continues with its normal startup process. The phone does not 
reset.

If you enter an invalid key sequence, the buttons no longer flash, and 
the phone continues with its normal startup process. The phone does not 
reset.

If you enter this key sequence correctly, the phone displays this 
prompt:

Keep network cfg? 1 = yes 2 = no

In order to maintain the current network configuration settings for the 
phone when the phone resets, press 1. In order to reset the network 
configuration settings when the phone resets, press 2.

If you press another key or do not respond to this prompt within 60 
seconds, the phone continues with its normal startup process and does 
not reset. Otherwise, the phone goes through the factory reset process.
