If this was a conversion to 9.2B done with 9.2B (161107 ) there could be a problem if the EFT Provider Code specified in the conversion was less than 6 characters long.
This was fixed in the Payables 9.2B (161208) Service Pack. Installing the SP should take care of the problem. If you continue to have issues, please contact Adagio Tech Support at http://softrak.com/support/techsupportoptions.php
Make sure that the TelPay details are set up under Edit | EFT Provider:
