5. Add the following code to the end of the file:

```php

exten => _X!,1,NoOp()

    ; Checking if there is a provider in the list.
    same => n,ExecIf($[ "${FIELDNUM(rrItem,\,,${PROVIDER_ID})}" == "0" ]?return)

    same => n,GotoIf($[ "${rrElement}x" != "x" ]?check)

    same => n,Set(rrArray=${rrArray}${i}:${GLOBAL(${i})})
    same => n,Set(i=${SHIFT(rrItem)})
    same => n,EndWhile
    ; Finding an item with a lower weight
    same => n,Set(rrArray=${SORT(${rrArray})})
    same => n,Set(rrElement=${SHIFT(rrArray)})
    same => n,While(1)
    same => n,ExecIf($[ $[${GROUP_COUNT(${rrElement})} < ${busyLevel}] ]?ExitWhile())
    same => n,ExecIf($[ "${rrElement}x" == "x" ]?ExitWhile())
    same => n,NoOp( ${rrElement} - is busy)
    same => n,Set(rrElement=${SHIFT(rrArray)})
    same => n,EndWhile
    same => n,NoOp(--- ${rrElement} ---)
    
    ; Checking whether the provider matches
    same => n(check),ExecIf($[ "${PROVIDER_ID}x" != "${rrElement}x" ]?Set(NEED_RETURN=1))
    same => n,ExecIf($[ "${PROVIDER_ID}x" != "${rrElement}x" ]?return)
    ; Increasing the counter
    same => n,Set(GLOBAL(${rrElement})=$[${GLOBAL(${rrElement})} + 1])
    ; The counter of active calls through the provider
    same => n,Set(GROUP()=${rrElement})
    same => n,return
```

{% hint style="info" %}
In the lines of the form "**Set(PUSH(rrItem)=SIP-1601534775)**", the ids of providers are listed, among which outgoing ones should be evenly distributed. The ID can be copied in the browser's address bar when editing the provider. The "**busyLevel**" variable defines the maximum allowed number of simultaneous calls through the provider.
{% endhint %}

{% hint style="warning" %}
For each provider, you will need to describe the outgoing route. The template in the routes must be the same.
{% endhint %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.mikopbx.com/mikopbx/english/faq/outbound-routing/number-templates/uniform-distribution-of-outgoing.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
