Hi Stefaan,

the documentation on this feature is indeed very poor.
I've set it up once and never changed the lines of code again (and i
also only created the announcements once).

> The calls are going over the RTPProsxy and the sound is now indeed being streamed by RTPProxy (only about 3 times too fast :) )
> Maybe the reason is that I used another box to encode the files  message.wav with makeann (from RTPProxy sources) to message.0 and message.8 or there is something else wrong with the format of the file.

> imvho the documentation of kamailio and the rtpproxy module is very clear , rtpproxy itself and especially the makeann program is poorly documented.

>> R callid from_tag to_tag

>> I have used the command  "  makeann behappy.wav behappy" to convert a
>> wavfile. It gave me a .0 and .a file which I have placed in the
>> /var/log/rtpproxy directory  (makeann comes with the rtpproxy source and is
>> rather a bit shy with information to say the least ;) )
>>
>> There is not too much information or examples found about this so I was
