[asterisk-users] cmdRecord issue related to "iax2 received mini frame before first full voice frame"?

[Novak Joe]

Hi,
  I tried sending this message a few months back but never lucked into
a response.  I thought I'd try one more time, juicing up the subject
heading a bit, as I am still seeing this behavior intermittently.

  I'm running several asterisk servers in combination with dundi.  The
servers are in different data centers, but other than that they are
running identical copies of the same os image, asterisk configuration,
etc.  One server acts as the trunk and is used to terminate pstn
calls, and pass them on to another server via dundi, which then
answers the call.
  I recently noticed that one of the call-answering servers was
responding and playing back voice prompts fine, but was failing to
record any user generated audio.  After opening up the CLI on this
server and running a test call through it, I noticed reams of the
following warning message any time audio was being played or recorded:
[May 21 20:31:52] WARNING[27346]: chan_iax2.c:8020 socket_process:

  I found the following related post:

  However this doesn't explain why I should be unable to record
anything.  The issue seems to be related to network activity, and I'm
not seeing it on any other servers.

  A more detailed explanation of what the above warning means/implies,
and how or why it might be preventing recordings would be greatly
appreciated.

  I'm running Asterisk 1.4.11 on debian Etch.

  Cheers
