Trouble using SIP to fax with the Fax Over IP enablement kit.

Product Name: VersaLink C7020/C7025/C7030 Multifunction Printer
Operating System: Not Applicable

I have a customer that has purchased and enabled the Fax Over IP kit for their Versalink machines, we went with Versalink primarily for this function, and we're uanble to get it to complete a fax successfuly. When testing it we get either error code 033-545 or 033-593. I feel like we're really close to getting this configured correctly but it's not something that I have setup before and we're finding the documentation to not be as helpful as we would like.


Additionally there is one other thing that was unexpected which we discovered and we'd like to know if the device is working as intended or if it's something that should be addressed by Xerox. When enabling SIP as our faxing protocol the LANFax, fax from desktop via driver, function in the driver disables via SNMP. I understand that this function is primarily intended to work with the analog fax function but it seems like the job should be able to queue and send over SIP as well. Afterall to change to SIP all we do is change the send method for the fax app in EWS.


Any support that you can provide in regards to either of these questions is greatly appreciated.
