[Spce-user] howto: compiling itp_MEDIAPROXY module on slicehost

[Andreas Granig]

Hi,

Thanks for the description, might indeed be helpful. I had some issues
on Amazon EC2 as well, and I'm going to provide a How-To hopefully soon.

Regarding the userspace rtpproxy, it should work out-of-the-box for
normal call scenarios, but it will break audio for voicebox and VCS
announcements and conference calls, because there the rtpproxy needs to
bridge between localhost and the outside, which is quite a pain to
configure in the kamailio config.
