Hello, there are some companies selling (proprietary) add-ons in this area for Kamailio, RTPEngine etc..
I know of some companies that also developed something for it inhouse and got it certified in Europe. It was not open sourced for obvious reasons, mainly because it contains some internal knowledge about processes and/or infrastructure. We had some open-source attempts on the Kamailio project side, but there were stopped also because of some "agencies" request I heard. In the end it boils down in implementing the ETSI standards and then having it certified for a specific setup. There is also this open-source project, which claims to be used from different providers. I don't have any particular experience with it, though: https://github.com/OpenLI-NZ/openli Cheers, Henning -- Kamailio & VoIP services – https://gilawa.com > -----Original Message----- > From: Phil Lavin via VoiceOps <[email protected]> > Sent: Donnerstag, 19.
