Elavon recently added default Business Rules (CVV, AVS and settlement) for all new account setups as of Nov 2017.
Below are instructions to follow, in order for your account to work correctly with Ivrnet's products and services.
Please go your Converage Login page and log into your Merchant Account Portal - also known as My Converage
After logging into Converge go to the Business Rules screen.
Delete both the CVV and AVS Business Rules
That's it! Thank you.
