Hi,

I know that this is not the purpose of the proxy but there is a situation in which our kamailio needs to playback early media for a small number of calls.

Which module will be most suitable for this?

One way is to use rtpproxy and just functions such asrtpproxy_stream2... to play back the prompts to the caller.

Note that the caller is not behind NAT or behind any symmetric firewall. So we a free to choose.



We know we could do it easily by dispatching to asterisk where we use the Progress() app or similar for freeswitch but we don't want add the overhead of a new media server installation and configuration.



We need a kamailio based one box solution.


Then you have to write your own module, since Kamailio by design does not handle media. Period.

It's like asking MySQL to implement a picture filter for filters stored in the database, it's just not in the design. Kamailio is a SIP server that works with many media servers, but it's not a media server.

Having said that you can propably fake a 183 and have a media server like SEMS do it, but adding Asterisk is pretty much the same.
