Outbound IP Fax not working. UM 421 with latest fax tool and on IOS 12.4.X. Per fax outbound troubleshooting:
I troubleshoot each component and saw that all works except sending fax to the gateway. Message tracking shows that it sends out to the world and not to the GW. I am not sure how to send it to the GW.
According to doc, there is a mx record with smtp connector but that is for 2 separate domains. I plan to try that next but was wondering if anyone got it to work with win2003 and exchange2003 offbox.
