[SR-Users] Any modules with LRN dipping capacity?

[KamDev Essa]

 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.

  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.

 For reference, this is how my lrn provder replies to a dns query:

; <<>> DiG 9.11.2 <<>> @enum.AnEnumProvider.com -t naptr 3.2.6.4.2.6.5.5.7.7.1.lrn.e164.arpa

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.
