The device attempted to communicate to the processor, but the processor did not answer.
Processor phone numbers are generally defaulted in PSCS, but some processors provide different dial-in numbers depending on the merchant, requiring the user that builds the PSCS file to enter them manually. If the device cannot communicate to the payment processor, the culprit is likely this number. Please log in to PSCS and verify with the processor that the processor phone number is correct. If the number is incorrect, update the PSCS file and initiate a Tran re-load to load the updated file. If the number is correct, contact Datacap tech support for further hardware troubleshooting, as it's possible that the internal modem may be malfunctioning.
