For Registration Servers choose from the list below. Best practice is to register to at least two servers from two different regions.
1.us-central.clearlyip.com
2.us-central.clearlyip.com
1.us-east.clearlyip.com
2.us-east.clearlyip.com
1.ca-mtl.clearlyip.com
2.ca-mtl.clearlyip.com
If your Server allows the use of SRV records you can use:
_sip._udp.us.clearlyip.com - UDP protocol with access to USA Servers
_sip._udp.ca.clearlyip.com - UDP protocol with access to Canada Servers
Scroll to the "Sip Credentials" section, these will be the Username and Password your PBX will use to Register to the Trunk Servers above.
If you are using the FreePBX Clearly Trunking module you will want to copy and paste the keycode below to paste into the module on your PBX as outlined here.
Scroll to the "Numbers assigned to this location" section, these are the numbers you selected during the account creation. You will need to use one of these for the Default Caller ID on your Trunks.
