Hello all,

Thank you all the participants to the conf call.

For the people who were not able to join us, please find the audio 

And keep in mind that whatever comment, objection, idea or generic 
feedback you may have on the topic we are working on for OpenSIPS 2.4 is 
more than welcome ;)

Best regards,

Bogdan-Andrei Iancu
   OpenSIPS Founder and Developer

>     (DTMFs, call status) from FreeSWITCH into OpenSIPS script or for
>     being able to control a FreeSWITCH call from OpenSIPS script via ESL
>   * *Asterisk flavored* Load-Balancing for a more realistic and
>     accurate traffic balancing over Asterisk clusters (as the load
>     information is fetched in realtime from Asterisk);
