STUN setting with DNS-SRV transport is not working

I configured STUN NAT traversal and configured stun.stunprotocol.org as my stun server with DNS-SRV as transport on all T-38P, T-28P, T-22P phones.

None of these phones seem to send CLASSIC-STUN request out when DNS-SRV setting is on. Irrespective of the phone type/firmware this problem persists.

With UDP transport, STUN request is out from the phone.
Find the zip attachment with phone configuration and pcap traces with both dns-srv setting and udp setting.
