Arrggh. I thought it was fixed, but now the problem has come back again.

I can see the outgoing audio packets, but I cannot see any incoming
audio packets.

Oh, OK need to use:

<action application="set" data="proxy_media=true"/>

Fair enough, the end phone is behind NAT.

But now while incoming audio is working, outgoing audio is not working.
Arrghhh!

tcpdump seems to show 3 streams:

* stream in from phone
* stream out to phone
* stream in from provider

But no stream out to provider.

How do I debug this?
