Hi Syed.
I don't believe the ATA190 is supported with CUCM / BE7K. The device is part of the Small Business range and appears to be a re-badged Linksys ATA.
I've checked on my CUCM 9.1 system and my 10.5 LAB and there is no ATA 190 in the device list.
Depending on where your analogue devices get patched back, you need to look at the VG2xx range.
ie VG202 - 2 port gateway, VG204 = 4 ports, VG224 = 24 ports, or the VG350 for high density analogue.
Licensing will be UCL Essential. The top-level SKU is R-UCL-UCM-LIC-K9. And the option is going to be under LIC-CUCM-9X-ESS-A (Qty 100)
Cheers
