Steps:
Login to secure online portal https://my.iplum.com.
Go to “Accounts || Select Account || Profile & Permissions”.
You will see different options you can edit.
Name: Click on the pencil icon next to it and update to new name. It can take up to 48 hours to propagate new Caller-ID name. Name is propagated only for local numbers. For Toll-free numbers it will show name as “Toll-free”
Caller-ID with Sub-Accounts: By default caller-id is the iPlum name and number on that account/sub-account but if you have sub-accounts and you wish to change the sub-account caller-id to another iPlum account caller-id within same team account, you can switch it here. Click on the pencil icon. Choose between user’s iPlum number or other iPlum numbers on the account.
Note: Most carriers would show both the caller name and phone number in the caller-id but some receiving carriers may show only the caller number with city & state based on their internal policies.
