Re: [sr-dev] [kamailio/kamailio] Added asynchronous offer, answer and delete rtpe functions (PR #3286)

At first look, this is not about async processing, but only suspending the transaction before doing the rtpproxy control command. There is no passing of a task to some async worker, nor resuming the transaction.

Practically your code does something like:

``` t_suspend(); rtpengine_offer()/_answer()/_delete(); ```

Maybe you can just to use `async_task_route()` for INVITE:

And use the rtpengine functions in the target routing block. It looks like what you want to implement inside rtpengine module, but you can achieve that by using async module.
