Wait, are we sure this is just a codec issue? Seems too simple.

The codec preference list sounds familiar; I feel like we did a similar question where prioritizing G.711 was key.

Increasing the bandwidth allowance seems like it could be overkill for a media negotiation issue. I'll have to think through the other choices more carefully.
