ATA 186, SCCP - It can't established TCP connection

Hi all!

I try to deploy ATA 186 via routed ip link. ATA uses SCCP image and should be registered on CME 4.1.

ATA 186 obtains IP info (and TFTP address) via DHCP. It successfully downloads all necessary configs.

There is no any filters on the path from ATA to CME. Also i connected PC with the same IP and made telnet CME_IP_Address 2000 and connection was successfully established. But it can't established from ATA. Could you help me with this problem.

Thank you in any help

Arseny
