Scratch the last email. Had it that only one of them dropped out and the other
kept working.

Another update:
In my testing I had two phone calls going simultaneously (one from my mobile
and one from my deskphone) and they both dropped out at virtually the same time.

Update:
Using tcpdump I managed to do a packet capture as the problem is unfortunately
occurring frequently enough to make this possible.
After looking at the pcap with Wireshark, the RTP stream looked fine and I
could not find any empty RTP frames e.g. all had payload entries and were the
same size. They were all G.711 PCMA encoded as well.
Surely it cant be a disk write issue otherwise I would probably be seeing other
issues and its usually intermittent?

Hmm the problem is still there after these changes and I have now stopped my
upgrades until its fixed.
After posting on the forum, jcolp has responded with:
--------
The two cases for format_wav to return an error for writing is:
1. It was given a frame with no data in it
2. An error occurred when writing it to the disk
The first case would require probably orchestrating things and going through
the complete media flow to determine where/how a frame with no data appeared.
--------
Any ideas where I would start my troubleshooting?

Hi Lonnie
Thanks for this.
So the testing I performed was to call into the system from my mobile to a
number that goes directly to voicemail without a greeting. If the call stayed
up for a couple of seconds then I would hang up and call again.
Whenever I got the Warning messages, the call actually dropped. Another log
line I didnt add was:
-- Recording was 0 seconds long but needs to be at least 1 – abandoning
I also posted on the Asterisk forum and someone mentioned that a solution to
the problem could be setting “transmit_silence=yes” in asterisk.conf which I
tried and it significantly reduced (possibly eliminated) the problem.
I will try setting this at a couple of our problem sites to see if it fixes the
problem and let you know how I go.
Regards

Hi Michael,
I looked through the Asterisk code, this is basic core code, but some 'code
stirring' has occurred between 13 and 16.
If you can replicate it in the lab, does Astlinux 1.5.0 / 13se work as expected
with your voicemail.conf?
Does the error occur only on long (longer) voicemails?
Does the error occur intermittently or all the time? Any pattern?
