I have a UC500 configured with a Linksys ATA SIP SPA 2102. Incoming calls via BRI. I have a number of Cisco phones connected to the UC500 and for now I have plugged in two analogue phones into the Linksys ATA.
Everything is working great, except soon I will change one of the analogue phones for a Fax. According to the Spec of the Linksys SIP ATA, it supports Real Time Fax over IP via T.38. Any ideas how to add support for this on the UC500? Also should this be reliable? Do I need separate configurations for incoming and outgoing Fax?
