[Fazarel]

• Device: observed with Pixel 3a (sargo) and Xiaomi Mi A2 (jasmine_sprout)
• Channel: stable
• Build: OTA-22

Steps to reproduce

Receive a voice message

Expected behavior

A correctly readable SMS notification informing of the message

Actual behavior

The SMS received displays code:

//VVM:SYNC:ev=NM;txt=You have received a new message, call XXX;id=XXXXXXXXXX;c=0000X;t=v;s=+XXXXXXXXXX;dt=15/05/2022 17:02 +0200;l=33

And after calling the voicemail, another SMS:

//VVM:SYNC:ev=MBU;c=00000

I don't think UT supports VoiceMail protocol. Meanwhile you can disable that feature from your provider.

Looks simple enough, is there a documentation somewhere? Also which carrier is that?

Exactly, I guess I didn't know what to look for. I guess a partial implementation would be displaying these nicely / in the correct conversation (per the number that called you instead of the voicemail one)? And a proper one would have a menu for interacting with the voicemail box (which looking at the spec is just IMAP)
