Hi Guys,
I have just tried registering to CUCM 10.5 a brand new Cisco ATA 190 straight out of a box with no success. Line 1 of the ATA has analog phone plugged in but its respective line registration status on the CUCM is still Unknown. The ATA has no issue on getting an IP via DHCP and getting all the configuration (eg, user id, extension.etc) from the TFTP server. However, the status of the ATA 190 Line 1 shows No line enabled along with a "Yes" for the Proxy registration status which doesn't reflect on the CUCM. Please see enclosed captured for details.
Please advise.
