Hi Mark, Thanks for the response. Now NS query is working fine!!
But I have one more query- we have our application to resolve e164 domain queries i.e NS, NAPTR and CNAME queries only. If user give any other query type then application sends RCODE=4(NOT_IMPLEMENTED) in response. But bind9 is rejecting our response and sends SERVFAIL. Attached is the PCAP. Please share your views again on this. Thanks in advance!

If it has followed/seen a delegation then the returned SOA record in the response needs to be at or below that point. I suspect that named has a cached NS RRset between e164.arpa and 4.0.4.5.2.4.1.4.2.0.2.4.e164.arpa which is causing the returned response to be rejected.
