If you have time soon, you can propose a PR with the option 2. Otherwise I will look into it whenever I get a chance, likely not today and not sure for the rest of the week. -- You are receiving this because you are subscribed to this thread.

Re: [sr-dev] [kamailio/kamailio] KEMI onsend_route method is not called (#1474)
In a pure KEMI script environment, printing `onsend_rt.rlist` gives
```

[sr-dev] [kamailio/kamailio] KEMI onsend_route method is not called (#1474)
### Description
KEMI onsend_route is not called unless there is a placeholder/dummy routing
block.
```
## without this block, core will never call KEMI->onsend_route
onsend_route {
## do nothing
}
```
### Troubleshooting
Reproduction
1. In KEMI create ksr_onsend_route(). Observe that this function is never
invoked.
2. Add a route block:
```
onsend_route {
## do nothing
}
```
Now observe, that KEMI ksr_onsend_route() is called.

### Possible Solutions
Not really a problem, just a surprise to the KEMI user. Possibly, document that
in order for the KEMI function to be called, the configuration file needs a
dummy routing block for onsend_route.
### Additional Information
The reason is the following logic:
onsend.h:
`ret=keng->froute(orig_msg, ONSEND_ROUTE, NULL, NULL);`
This line is called only if `onsend_rt.rlist[DEFAULT_RT]` is non-NULL, but this
array is initialized only if the `onsend_route` block exists.
