### Description

Currently calling `route()` within the `onsend_route` will cause kamailio to fail to start with an error that `command not allowed in onsend_route`

### Expected behavior

While there is a limited amount of functions that can be allowed within the `onsend_route`, calling `route()` here would be done simply for code organization.

#### Actual observed behavior

Kamailio fails to start;

### Possible Solutions

Allow `route()` to be called from `onsend_route`.
