The answer, then, smiles out straightforwardly:
https://kamailio.org/docs/modules/5.1.x/modules/enum.html
But a SIP redirect/RFC 4694 interface would be easier to deal with and is more commonplace.
Neither require a special module. Modules perform technical functions that otherwise require a lot of work in route script, or where functionality is required that may not be exposed in generic route script constructs.
An LNP query via ENUM or SIP redirect may serve a business-specific function, but it's still just an ENUM query or a SIP redirect.

Thats fine. I can always add a host file entry for an IP. But I still do not get where I need to have the domain name in the request.

What is queried when you use enum_query() as you'd expect to?
You might have to take a packet capture to determine that.

I need the "rn" from the answer back so that I can use that in my LCR processing in case the TN is LNPed. Today there is a high percentage of LNP TNs out there. KD On Tuesday, May 22, 2018, 1:21:42 PM EDT, Alex Balashov abalashov@evaristesys.com wrote:

Also, 'rn' sounds like the LRN attribute as described in RFC 4694. That would be a SIP redirect, not an ENUM query. Are you sure you're not confused about which query interface you're using? Moreover, it's possible your LNP provider provides both redirect and ENUM-based query interfaces; that's common. If that's the case, go with the redirect.

So he needs to send the naptr query to a specific host, and to grab and unpack the answer to get the rn.
To the OP, I suspect the only good way to do that with kamailio is to use one of the Turing complete modules (perl, lua, python or the like) to write the necessary code.
Or write your own kamailio module.
The answer is likely the same when using a web-based api to do the dips.

James, Thanks great example. I think I will go with http_query(url, result) route because I am not as savvy @ python or lua as I am on C# over .NetCore. Yes I can see delays with the two resource hop. I am hoping its not too much. KD

By going http_query I could kill 2 birds with 1 stone.
- dip LRN - dip db and get composed LCR string for my Contact header.
Then Kamailio just update the contact header and replies 300 back and we are off to the races. Basically moving business logic off kamailio and keeping it lean and mean. KD
