Disable Account Codes
When Account Codes is disabled at the account level, it is also disabled for all SIP trunks. To disable Account Codes for an individual SIP trunk, go to the trunk settings and uncheck "Enable account codes". To disable it for the account, follow the steps below:
Go to the Account Codes page.
Under Account Codes Settings, toggle off Allow account codes and click [Save].
Click [Save] to disable Account Codes for all SIP trunks on the account. The account codes are preserved, so they can be used again if the feature is re-enabled later.
