As my previous comment mentions, we could certainly use more information.

Expect that we need to reproduce the issue in order to investigate it. That means we require the debug mentioned and your configuration files (only what is necessary to reproduce the issue). That could be sip.conf or pjsip.conf, dialplan such as extensions.conf and maybe voicemail.conf. 

You should build a minimal test scenario where you can reproduce the issue and then post the necessary files here and describe how to reproduce.

> When either calling into the voicemail application directly or being transferred to voicemail (i.e. when called party is unavailable), none of the voicemail prompts can be heard.  Looking at the Asterisk console, it is evident that it is being processed, but there is no audio.
> This is a regression introduced in Asterisk 13.4.0 and, so far, appears to affects only Grandstream phones.  The specific models we have that I've tested against are GXP2000 and GXP2020.
> So far, no other IP phone (Snom and Digium) or softphone (Jitsi) I've tested against has an issue with voicemail and 13.4.0.
> Reverting to 13.2.0 resolves the issue.
> I'm not sure what else may be required to help track down the issue.  I tried debugging RTP in the console and I do see communication between the phone and Asterisk; therefore, Asterisk must be sending some malformed bit of data that's causing Asterisk to ignore the stream.
> Let me know if there's some additional bit of info that's needed.
