@beyolf said in Status of VoLTE (Voice over LTE 4G) implementation?:

@jgalaxy
As far as I understand it, the problem is not ofono but that in order for VoLTE to work properly there a lot of IPC needed with the cellular module and that is proprietary so it's hard to figure out.

It's more of a stack that does a SIP-ish type transaction. You need an additional 3GPP stack like Doubango to scoop up your voice signals, do call signalling, and deliver the other side's voice data to you.

Some of the solutions use firmware in the comm module to do this (The IoT modules doing VoLTE) or you need a stack. Shrug. Doubango compiles inside my Yocto build environment as a recipe now, but I need to clean up the mess I have to get there. I'm kind of wondering where UBPorts is on this score so I can either lend a hand or to straighten out the problems I have (All ships rise in the tide...)
