I *think* that this issue will resolve if Voipo will be willing to proxy the audio for my calls. OTOH, I do not know what new issues doing so will bring up (aside from more load on their system and possible latency in my calls). I've floated the suggestion to Support - we'll see what they have to say.
That could definitely be it. Some of our vendors only support G.711.
