Getting Visual Voicemail working on L5 on Byzantium

I am trying to set up VVM, finding the documentation Carrier Notes · Wiki · Chris Talbot / vvmplayer · GitLab makes me realize that VVMD & Virtual Voicemail won’t work for T-Mobile with VVMD in Byz being 0.12 and the requirement being CURL 8.2.0 and VVMD 0.16 or greater

@kop316 should be able to provide detailed support instructions for you.

Although, I do get a Voicemail Return text… So something is working

Honestly my assumption is that my deps and software aren’t new enough versions to allow for this to work…

Okay, maybe byzantium-updates-proposed can help you out:

sudo apt edit-sources

Choose either GNU Nano or Vim (1 or 2), then add this line:

deb https://repo.pureos.net/pureos byzantium-updates-proposed main

Then:

sudo apt update && sudo apt upgrade

I’ll give it a shot

Nope, no dice on that… Assuming I will have to grab the packages from source and manually build them.

Can I try adding curl 8.2 manually and keep the current version 7.74?

I do not think so, not unless it can be containerized.

So realistically I’m gonna await 'till Crimson

The versions for curl and vvmd on Crimson do not meet your requirements:

curl/landing 7.88.1-10+deb12u5 arm64
vvmd/landing 0.14-1 arm64

I assume you will need to use Mobian ‘Trixie’ instead.

Okay, I’ll add Mobian’s “Trixie” repo and install curl and vvmd

Did you ever get this to work? I tried installing the correct versions of vvmd and curl about a year ago and broke the phones software.

No, Mobian is likely a necessary step in the process.

I flashed a phone with crimson and installed curl and vvmd from Debian bookworm backports. In the process it also installed vvm version 2.1. The app downloads incoming voicemails and send a notification so the app is working. The problem is not a codec to decode amr files. I installed Clapper and FFmpeg from Debian main repo and now it all appears to work. I haven’t run into any new issues with the phone’s other software. I’ll post here if something breaks.
