I apologize for asking unit questions today and decided to just present the big picture and address what I am trying to get @ holistically. I want to implement a custom LCR only solution on kamailio. INVITE in 300 out. Nothing else. I expect awesome cps stats that makes we lean towards kamailio rather than throwing up a home grown SIP server and worrying about performance. I have the guts of the LCR logic down pat, but todays its manual. In my process I do the following : - Check LRN of the requested user. I use dig doing a ENUM call. - Use the requesting user and LRN of requested user to mediate call type. Local or Interstate using LRN check via ENUM call (above) and LCAD data lookup. I use sql query. - Mediate call type Intrastate or International if not Local or Interstate using LERG lookup. SQL query too. - dip into database with requesting user and call type and get N lists by costs ascending. SQL query. - Construct Contact info in db or kamailio. - Send 300 reply will contact having the various routes. I can automate 2 through 6 using Kamailio. Basically xquery with supplied data and deal with the Contact header with data received. 404 or default route if no data received.
I cannot handle the ENUM in kamailio or mysql. The provider does not provide SIP redirect. What are my options, besides changing LRN providers? KD

How did you draw that conclusion?
In the LRN request via ENUM using dig I provide an IP of my LRN dip provide and a E.164 formatted TN of the requested user. I get a text dump from which I extract the rn value if present. I dont not know how to automate those steps or other steps to get the same solution. KD On Tuesday, May 22, 2018, 2:53:53 PM EDT, Alex Balashov abalashov@evaristesys.com wrote:

Hello,
if the enum module somehow does not work for you, maybe you could think of adding some python or lua code. You could exec with python_exec e.g. a DNS query and put the result in a pseudo-variable. Just an idea, not tested obviously.

Awesome. Where can I get info on shelling out to run a lua or python script and getting data. That could very well be a quick and dirty option if its not to bad on performance stats. KD On Tuesday, May 22, 2018, 3:05:08 PM EDT, Henning Westerholt hw@kamailio.org wrote:

On the app_python. How do I get the value of rn back to to kamailio. does the function return a value? likern = python_exec("my_python_function", "$rU");and evaluate rn later in teh script? KD

It does not return a function, but it can set variables and manipulate message values within the API exposed into Python:

Again: DNS-based resolution mechanisms make use of a global DNS hierarchy, so you need to figure out how to expose your LRN provider's e164.arpa. zone into your local DNS resolver.
Shouldn't be too hard. You can configure most DNS caches like PowerDNS to source a particular zone from a static upstream.

@ the risk of sounding ignorant, I have configured DNS in the IT world for a while. Its either in DHCP, static or host file. I have never had reason to configure DNS to source a particular zone from a static upstream. But I would like to learn. Is there an info on the net to do this. KD

There doubtless is. Google "dns conditional forwarding".
