Hello Brian,

I have added
<param name="inbound-codec-negotiation" value="greedy"/>
to internal and external conf.
We have only allowed one codec now (G711A)

Conferencing MOH is fine. However hearing the other party (Fritzbox is
almost impossible).
Hearing voicemail announcements is also very choppy with seconds of delay.

So, in one case it works fine, in other s not.

Any more hints?

Best regards
