asterisk users - Jul 2004 - 'Dropping voice to exceptionally long queue on IAX2'

I searched the archives and found a couple references to this from Mark. I
am on a network that will not support IRC (govt) so I cannot do IRC.

This happend after calling Voicemail (<num>). I hung up on the call and
also
tried the # to hang up. Both resulted in many, many
'Dropping voice to exceptionally long queue on IAX2' until I physically
hung
up the line.

It seems the detection of the hangup on voicemail using the hard hangup
(handset) even took a good 10-15 seconds to register.

I am running Asterisk CVS-07/13/04-09:44:05  with my patch to app_voicemail
that I put on the list earlier.

I have also tried the unpatched app_voicemail and have the same results.
