Hi Juha,

I see the typo, I will correct it next time I improve the module.

No Kamailio processes are blocking, one thread is started for each call / media stream the thread is running a "ticker" that is processing all the samples in the audio streams.

Here is an example of the audio stream running in the thread

transmit :

FilePlayer >> Resampler >> Encoder >> RTP Send

In the same thread the received stream is runned

receive :

RTP Received >> Sink

A small typo here:

2.1. Kamailio Modules

The module depends on the following modules (in the other words the
listed modules must be loaded before this module):
* tm - accounting module

A question:

Is rms_play() done asynchronously or does it reserve the K process that
handled the request for the duration of the play?
