### 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`.
