[Pdns-users] Using Power DNS for ENUM Server and 408 Error

[Robert Dawson]

Have you done packet captures to make sure that the reply is leaving the PDNS server and reaching the SBC?

 

Any firewall between the two devices? Any egress filtering on the PDNS server? ACL or ingress filtering on the SBC?

I have a  powerdns server setup using mysql on the backend.

 

The PDNS logs see the query come in:

 

SELECT content,ttl,prio,type,domain_id,disabled,name,auth FROM records WHERE disabled=0 and name=someEntry' and domain_id=3

 

But my SBC times out.

 

Jul 11 15:19:59.440 [DNS] (2) Q:NAPTR someEntry  process ENUM results 408 Request Timeout

 

 

If I do a dig:

 

dig @myServer SomeEntry NAPTR

 

I get a good answer:

 

someReverseEntry. 120 IN NAPTR 100 10 "u" "E2U+sip" "!^.*$!sip:someEntry at someIP!" .

 

 

I have a domain set in the domains table with an id that matches the query (3)

 

|  3 | someDomain.com | 127.0.0.1 |       NULL | MASTER |            NULL | NULL    |

 

I have confirmed that auth=1 on the record.

 

Any other information you need to assist?  Let me know.

 

Thank you
