We will show you in this article how to find the recommended POPs as well as some tricks in case it is not working accordingly.
Finding the recommended POPs
You can find it in your portal by following the steps, or by heading to this link Recommended POPs
From your customer portal, head into DID Numbers, Manage DIDs
Followed by editing your DID with the yellow button on the left side of your DID Number
Head down the page until you reach DID Point of Presence and look for the servers with a green check.
Select the one you wish to use, head down the page and press save. Once done, make sure to configure your device to the same server you have selected for your DID.
To know how to access your device and make the change, look at one of the following options depending on your device
I register and inbound and/or outbound is not working! What do I do?
- If you use the DNS of the server (montreal1.voip.ms for example), change the setting in your device to use the IP address instead. The IP addresses of the recommended servers can be found by following the steps above. Each recommended server will have its IP right next to it. This can also be fixed by performing a DNS Flush on your network.
How to perform a DNS Flush
- On Win10: Go to Start and type CMD (command) and right click on it to open as admin (CMD opens), then please input the following command: ipconfig /flushDNS
- On Mac: Press Command+Space, type in Terminal (Terminal opens), then input the following command: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
- On ATA / IP Phones: Disconnect for a good 3-5 minutes and reconnect. If it persist, try doing a full network restart and if it persists, use the IP address.
- On PBX: Restart asterisk. If still the same, use the IP.
- On iOS Mobile Devices: Reboot your device.
- On Android Mobile devices: Open Chrome, then please type chrome://net-internals/#dns in the URL field, then in the left pane click 'DNS' and lastly click on Clear host cache button.
Outgoing is not working
- If you have followed the previous step, incoming calls are working but not outgoing, make sure to verify your POP restrictions. This can be seen for the main account under Main Menu, Account Settings, Security.
For Sub Accounts, under Sub Account, Manage Sub Accounts, edit the sub account, under Security.
