Install Kamailio and add LRN and Juridictional routing over LCR on Kamailio

Hi
we need to install and configure Kamailio to be able to manage custumer and provider the routing logic will be made in Kamailio we will route the call per prefix to LCR and add LRN and Juridictional routing on Kamailio to be able to make it working we will use SIP 302 Redirect
and about to the juridictional i will provide the DB and the function you will mybe need to tune it
also we will need to add 1 table on the db to manage the LRN provider and hes credit
each query to this provider will be charged at the query rate off hem
we will also need to add the lrn on the cdr table
We will need to add on The Rate Table Inter and intra
We will need to add on the LCR table another information TYPE USA OR A2Z
We will Create new Table named Local_LRN where we will insert the result off the LRN query Provider with the date and the time off whene we make the LRN query
on the custumer and provider table we will add 3 others information
A: USA ROUTING : True or False
B: LRN_Routing True or False
C: Max Rate type Double
D: Re_DIP_LRN: The date where the custumer will like to remake the LRN Query else if the date are not expired the query are made in local

On the import Rate if the lcr type are A2Z we will insert on intra inter and rate the same value
On the import Rate if the lcr type are USA we will insert the rate deck with all information inter intra indeterminated
Also we well adapt the routing on kamailio to use that information befor to use any lcr the routing will determine first if the custumer DONT need USA Routing we going directly to lcr
Else if Custumer need USA ROUTING== True then we check USA Routing option B: C: D:
If Is need LRN routing we will first query ur Local_LRN table to see if there is any records where the expiration date dont past RE_DIP_LRN off the custumer if there is Result we will goto Checke witch Rate we will use Inter Intra or Indeterminate then we will proced to the routing over lcr where we will make sure to add on the where we will not accept call where the call rate > MAX_Rate off custumer and Provider
If is not need lrn routing we will then define if the call will be charged as inter or intra then we will be able to make to adapt the query

if you can make this working i will have many others jobs for you
Please contact me if you think to be able to make it
