Phones
How do Weave phones connect to the internet? Which two servers do phones try to connect to?
They grab an IP address from the offices private network and then try to connect to Weave's and Yealinks provisioning servers.
What is the difference between LAN and WAN?
LAN is local area network, it's a small area network like your home or office.
WAN is wide area network, it's a network that spans a wide area. Examples are, bank ATMs across the nation connected on the same network/system and the internet.
What's the first step in getting the phone to register?
Making sure it gets an IP address
What is a MAC address?
It's the unique identifier for a device and company. The first six characters of a MAC address are is the companies unique identifier, while the last six characters are the unique identifier to that specific device. There are no two same MAC addresses.
What's the difference between a Static IP and a Dynamic IP
Static IP: This one always remains the same and has to manually be assigned by a network-savvy person to the device. That IP will never change unless they restructure the network or the device is decommissioned.
Dynamic IP: It's automatically given to the device by the router when it connects to the network. Usually, it has a lease of about 3-5 days, after that time passes, the IP address of that device will change.
What is a Switch and what does it do?
A switch is an extension to the router. It connects to the router, provides additional ethernet ports so that other devices can get an internet connection.
What's the second step in making sure the phone connects correctly?
Phones will ask the ISP DNS or Google DNS to connect them to Yealinks provisioning server and PDS.
What is the process to troubleshooting phones not registering?
Click the OK button to verify if the phone is getting an IP address
Make sure the MAC address or MAC addresses are all in PDS under the Devices tab.
If it's grabbing an IP address and the MAC is in PDS, grab all IP addresses and slack the OBTech-team channel to get someone to provision the device(s)
What does NAT stand for and what does it do?
NAT stands for Network Address Translation. It works by changing a public IP address into a private IP address. Single NAT is what is always preferred for Weave phones to work correctly.
What does a modem do?
A modem grabs a public IP address (your access to the internet) from your ISP in order to supply your network with internet.
What are steps three and step four in getting the phones connected?
The phone will get connected to Yealinks provisioning server first, reboot, then connect to PDS.
What is the process to troubleshoot phones not getting an IP address?
Plug it into an ethernet port
Plug it into another ethernet port because the first ethernet port may be offline.
Plug it directly into the router to bypass any managed switches or equipment blocking the phone(s)
Static IP address the phone to manually assign it an IP address
Explain to the customer to contact their IT to check why the phones aren't getting an IP address.
What does DNS stand for and what does it do?
DNS stands for Domain Name System. It changes words that you type into your browser into IP addresses because everything on the internet uses IP addresses to load and connect you to the right location.
What does a router do?
A router routes the internet to all the devices connected to the network and it also does a NAT changing the public IP address received from the modem into a private IP address. Doing this will allow all new devices on the network to get a private IP address. It's also a firewall that has certain rules which will allow certain things into the network.
What's step five in getting the phones connected properly?
The phone will ask the DNS to connect it to PDS for an update. MAC address MUST be in PDS for this to happen.
